Botox in the Dental Office: Why Dentists Bring a Different Perspective to Facial Aesthetics and Jaw Function

For many people, Botox and dentistry may not seem like an obvious combination. Dentistry is associated with teeth, gums, restorations, and oral health. Botox is usually associated with facial lines and aesthetic medicine. But that separation overlooks something fundamental about modern dentistry: dentists work with the face every day.

We evaluate smiles in motion. We study facial symmetry, lip position, muscle activity, jaw function, tooth display, facial proportions, and the relationship between the teeth and the tissues surrounding them. We routinely administer injections in highly detailed areas of the face and mouth and spend our careers learning anatomy that extends well beyond the individual tooth.

That does not mean every dentist should administer Botox, nor does it mean Botox belongs in every dental treatment plan. Appropriate education, training, state regulations, diagnosis, informed consent, and understanding of facial anatomy are essential. The American Dental Association itself offers continuing-education programs covering botulinum toxin, facial anatomy, neurophysiology, patient evaluation, treatment planning, dosing, injection techniques, safety, and complication management, while emphasizing that dentists must follow their individual state’s scope-of-practice requirements.

What it does mean is that Botox in a properly trained dental office can be approached from a distinctly dental perspective—one that considers the entire smile rather than an isolated wrinkle.

That is the approach I take in my Henderson, Nevada practice.

“When I evaluate a face, I don’t see individual lines, lips, teeth, and muscles as separate things. I see relationships. A beautiful smile works because all of those elements belong together.”

Why Would a Dentist Offer Botox?

The simplest answer is anatomy.

Dentists spend their professional lives working within the oral and maxillofacial region. We evaluate muscles responsible for chewing, jaw movement, facial expression, lip position, and smile dynamics. That provides an interesting perspective when Botox is incorporated into facial aesthetic treatment.

A cosmetic concern that appears to be about a facial line may actually involve repeated muscular movement. A patient’s smile may be influenced by tooth position, lip movement, gingival display, facial proportions, or several of those factors simultaneously. And a patient complaining about a powerful jaw, clenching, or muscle tenderness presents an entirely different diagnostic problem.

Botox does not replace dental diagnosis.

It makes diagnosis more important.

Botox Is a Neuromodulator

Botox is a trade name for a formulation containing onabotulinumtoxinA, a botulinum toxin type A neuromodulator.

When appropriately injected into a targeted muscle, it temporarily interferes with the nerve signals responsible for muscle contraction. The treated muscle therefore contracts less forcefully for a period of time.

That mechanism explains why Botox can soften certain facial lines created by repeated muscle movement. But it also explains why botulinum toxin has attracted attention in areas involving excessive or unwanted muscular activity.

For a dentist, that naturally brings the conversation back to the muscles of the face and jaws.

The Dental Difference: We Begin With the Smile

Facial aesthetics can easily become a collection of isolated treatments. A little Botox here. Filler there. Whitening somewhere else.

I prefer to begin differently.

When a patient sits in front of me, I look at the face at rest and in motion. I want to see the patient speak and smile naturally.

How much tooth is visible?

How does the upper lip move?

How much gum shows?

Are the teeth proportionate?

Is the smile symmetrical?

Does one side of the face move differently from the other?

Are certain muscles unusually prominent?

How does the lower face relate to the upper face?

Does the concern actually require Botox or would changing something else produce a more natural result?

That final question may be the most important.

Good aesthetic treatment is not about finding another place to inject. Sometimes good treatment means not injecting at all.

Botox Should Never Be a Paint-by-Numbers Procedure

Faces are not standardized.

Two patients can point to exactly the same area and require very different treatment strategies.

Muscle strength varies. Facial anatomy varies. Eyebrow position varies. Smile dynamics vary. Previous treatment matters. Age matters. Sex can influence facial characteristics. The patient’s desired outcome matters enormously. Even subtle anatomical differences can influence where treatment should or should not be performed.

This is why I do not believe Botox should be approached as a predetermined number of units placed into identical dots on every patient’s face. The injection itself may take only moments.

The judgment behind the injection is where the real treatment occurs.

“My goal is never to make someone look treated. I want movement, expression, teeth, lips, and facial proportions to continue looking like they belong to the same person.”

Botox and Dynamic Facial Lines

Some facial lines are strongly influenced by repeated muscle movement. When we frown, squint, concentrate, raise our eyebrows, or make other expressions thousands of times over many years, the skin repeatedly folds along similar patterns.

Neuromodulator treatment can temporarily reduce the muscular activity responsible for selected dynamic lines. The objective does not have to be a frozen face.

In my practice, I prefer a more conservative philosophy: soften what is distracting while preserving what makes the face expressive. The correct endpoint is highly individual. Some patients prefer greater movement; others want a stronger effect. That discussion should happen before treatment rather than after it.

Botox and the Smile

This is where dentistry and facial aesthetics become especially interesting. A smile is not created by teeth alone.

The teeth provide one component. The gums provide another. The lips frame the teeth, while facial muscles determine how that frame moves.

Consider excessive gingival display—a “gummy smile.”

There are several possible reasons someone may show more gum than desired when smiling. Tooth size and shape, gum position, skeletal relationships, tooth eruption, and upper-lip movement can all contribute. Those causes are not interchangeable.

In a carefully selected patient whose excessive gingival display has a significant muscular component, a neuromodulator may sometimes be considered to reduce excessive elevation of the upper lip.

But if the real problem is related primarily to gum architecture or tooth proportions, injecting a muscle does not correct the underlying issue.

That is precisely why diagnosis matters.

Botox can modify muscle activity. It cannot make every smile problem into a muscle problem.

Botox and Facial Harmony

One of the most important concepts in cosmetic dentistry is proportion.

A beautiful veneer does not exist independently from the lips surrounding it. Beautiful teeth can still look artificial when their size, shape, brightness, or position conflicts with the face.

The same principle applies to facial aesthetics. Rather than treating a forehead, lip, jawline, or smile independently, I prefer to ask how the treatment affects the whole face.

Does softening one area make another area disproportionately prominent?

Could too much treatment alter eyebrow position?

Could changing muscular movement influence the way a patient smiles?

Would additional treatment actually improve the result or simply make the person look more treated?

These questions are particularly important because natural facial aesthetics depend as much on restraint as intervention.

What About Botox for Jaw Clenching and Bruxism?

This deserves a much more nuanced discussion than it usually receives online.

Botulinum toxin type A has been studied for bruxism, masticatory muscle pain, and certain temporomandibular disorders. Some research has reported reductions in pain, bruxism events, or bite force, but the literature remains heterogeneous and conclusions are not uniform. A 2025 overview of 14 systematic reviews found that many studies reported improvements in pain and bruxism-related outcomes, while other systematic reviews have found inconsistent or statistically insignificant advantages over placebo or conventional therapies.

A 2025 review focusing on lingual and oromandibular dystonia and bruxism similarly reported improvement in involuntary movement and pain in many studies, while also emphasizing adverse effects and limitations in the available evidence.

That uncertainty matters.

Botox should not become shorthand for:

“My jaw hurts, therefore I need injections.”

Jaw pain can have multiple causes. Clenching and grinding are complex behaviors. Temporomandibular disorders encompass different conditions rather than a single disease. In fact, a recent clinical review concluded that botulinum toxin is not considered first-line treatment or standard of care for TMD, emphasizing appropriate diagnosis, conservative treatment, patient selection, and the need for additional long-term research.

That is exactly how I believe the subject should be presented to patients.

Botox Does Not Cure Bruxism

This is another distinction worth making. Reducing the force generated by a muscle is not necessarily the same as eliminating the underlying behavior responsible for clenching or grinding.

A patient may still require evaluation of tooth wear, bite forces, damaged restorations, sleep-related issues, stress-related behaviors, muscle tenderness, and other contributing factors.

A protective oral appliance may be appropriate for some patients. Other patients require different management.

There should not be an automatic Botox protocol for everyone who grinds their teeth.

“When a patient tells me they clench or their jaw hurts, the first question isn’t where should I inject? The first question is why is this happening?”

— Marielaina Perrone, DDS

Why the Masseter Muscle Gets So Much Attention

The masseter is one of the primary muscles involved in chewing and closing the jaw. In some people, the masseter muscles can become quite prominent. This may be associated with powerful muscular activity, habitual clenching, individual anatomy, or simply natural facial structure.

Reducing masseter activity with botulinum toxin can sometimes decrease muscle prominence over time, which may alter the apparent width or contour of the lower face. But once again, anatomy matters.

A wider lower face is not necessarily caused by large masseter muscles. Skeletal structure, fat distribution, skin laxity, and other tissues contribute to facial shape. Treating a muscle when the muscle is not the primary cause of the concern is unlikely to produce the desired result.

Botox Is Not a Substitute for Dental Treatment

This may sound obvious, but it becomes increasingly important as dental and facial aesthetic treatment overlap.

Botox cannot repair a fractured tooth.

It cannot restore enamel lost from grinding.

It cannot replace a missing tooth.

It cannot correct periodontal disease.

It cannot make an unstable bite stable.

And it cannot undo damage to restorations caused by years of excessive force.

If someone has severe wear, cracked teeth, failing restorations, or other consequences associated with parafunctional activity, the dental consequences still need to be evaluated. Neuromodulation may sometimes become part of a larger strategy, but it should never distract us from the teeth themselves.

Botox and Cosmetic Dentistry Can Complement Each Other

This is one area where providing facial aesthetics within a dental environment can make sense.

Suppose a patient wants a more youthful or harmonious smile.

The answer might involve whitening.

It might involve orthodontic movement.

It could involve bonding or porcelain veneers.

It may require improving gum contours.

Or the teeth may already be beautiful, while the patient’s concern involves the way the lips or surrounding facial muscles frame the smile.

Sometimes several modest treatments create a more natural result than dramatically changing one feature. The goal is not to make the teeth compete with the face. It is to create harmony between them.

Why More Treatment Is Not Necessarily Better Treatment

Neuromodulators are temporary, which can create a temptation to think of them as low-consequence procedures. I don’t see them that way.

Temporary does not mean trivial.

The muscles being treated perform real functions and influence facial expression. Injection location, depth, dose, anatomy, and diffusion all matter.

Potential adverse effects vary with the treatment area and can include bruising, discomfort, asymmetry, unintended muscle weakness, headache, altered expression, and other complications. More serious adverse effects are possible, which is why proper medical history, informed consent, dosing, technique, and patient selection are essential.

This is a medical procedure. It should be treated like one.

The Consultation Matters More Than the Syringe

Before Botox treatment, I want to understand what the patient actually dislikes. That sounds simple, but it is surprisingly important.

A patient may say, “I want Botox around my smile,” when what actually bothers her is the color of her teeth.

Another may request treatment for a gummy smile when the underlying issue is tooth proportion or gingival architecture.

Someone else may ask for masseter injections because social media told him they would create a narrower jaw, despite having a facial shape primarily determined by skeletal anatomy.

And another patient may come in asking for facial rejuvenation when a small amount of conservative treatment is exactly appropriate.

The treatment should follow the diagnosis—not the trend.

Can Dentists Administer Botox?

The legal scope of practice for dentists varies by jurisdiction, and training requirements can differ substantially.

The ADA specifically advises dentists to consult their state dental boards because not every state permits dentists to administer botulinum toxins in the same circumstances. The ADA’s own current training programs emphasize facial anatomy, neurophysiology, evaluation, treatment planning, dosing, documentation, injection technique, safety protocols, and complication management.

So the meaningful question is not simply whether someone has “DDS” after their name.

Patients should consider the clinician’s education, hands-on training, knowledge of facial anatomy, experience, treatment philosophy, understanding of complications, and ability to recognize when treatment is inappropriate. That standard should apply to every professional administering injectable treatments.

Why I Offer Botox in My Henderson Dental Practice

For me, incorporating facial aesthetics into dentistry was not about transforming a dental office into something unrelated to dentistry.

It was an extension of something I was already doing every day:

studying smiles.

Cosmetic dentistry taught me to evaluate tooth proportions, symmetry, negative space, gum architecture, lip position, facial midlines, and the way a smile changes a person’s appearance. Facial aesthetics expanded that perspective outward.

Instead of stopping at the teeth, I can evaluate how the smile interacts with the face around it.

That is especially valuable for patients who want subtle treatment.

They usually do not want different teeth, different lips, different cheeks, or a different face.

They want to look refreshed.

They want their smile to feel balanced.

They want people to notice that they look good without immediately knowing why.

That is a very different aesthetic objective from simply eliminating every visible line.

Botox in Henderson, NV: My Philosophy Is Conservative

At my Green Valley practice in Henderson, Nevada, serving patients throughout Henderson and the greater Las Vegas Valley, I approach Botox the same way I approach cosmetic dentistry.

Start with the person, not the procedure.

Understand the concern.

Study the anatomy. Determine what is actually causing it.

Choose the least amount of appropriate treatment capable of producing a meaningful result. Then know when to stop.

A face should retain character.

A smile should retain personality.

And aesthetic treatment should support both.

Frequently Asked Questions About Botox in the Dental Office

Why would I get Botox from a dentist?

Dentists receive extensive education in the anatomy and function of the oral and maxillofacial region and routinely evaluate teeth, jaws, lips, smiles, and facial relationships. Dentists who provide Botox should also have appropriate additional education and hands-on training specific to neuromodulator treatment.

Does Botox from a dentist work differently?

No. The medication’s biological mechanism does not change because it is administered in a dental office. The potential difference is the clinician’s perspective, treatment planning, training, and understanding of the patient’s dental and facial anatomy.

Can Botox help a gummy smile?

It may be considered in carefully selected cases where excessive upper-lip movement contributes significantly to gingival display. However, gummy smiles can have dental, periodontal, skeletal, and muscular causes, so proper diagnosis should come first.

Can Botox treat TMJ?

“TMJ” is often used casually to describe many different jaw symptoms, but temporomandibular disorders have multiple possible causes. Botulinum toxin has been studied for certain muscular TMD conditions, but evidence remains mixed, and it is not considered a universal or first-line treatment for TMD.

Can Botox stop teeth grinding?

Botulinum toxin may reduce the force generated by targeted chewing muscles and research suggests potential benefits in selected bruxism patients, but it should not be described as curing the underlying behavior. Evidence remains variable, and diagnosis is important before treatment.

Will Botox make my face look frozen?

That is not my aesthetic goal. Dose, placement, anatomy, muscle strength, and treatment objectives influence the result. My preference is conservative treatment intended to soften selected muscular activity while maintaining natural expression.

How long does Botox last?

The effect is temporary. Duration varies among individuals and by treatment area, dose, muscle activity, and other factors. Repeat treatment may be necessary to maintain an effect.

Is Botox safe?

Botulinum toxin has established medical uses, but injections are not risk-free. Side effects and complications can occur, and risks vary depending on the treatment area and patient. Treatment should involve appropriate medical screening, informed consent, anatomical knowledge, dosing, and professional training.

Can Botox be combined with cosmetic dentistry?

Yes, when clinically appropriate. Facial aesthetics and cosmetic dentistry can sometimes complement one another because teeth, gums, lips, and facial muscles all contribute to the appearance of a smile. The important question is whether combining treatments actually improves the result rather than simply adding procedures.

How do I know how much Botox I need?

There should not be one standard amount for everyone. The appropriate treatment depends on anatomy, muscle strength, treatment area, desired result, previous treatment, and other individual factors. Evaluation should determine the treatment plan.

The Most Important Question Isn’t “Can Botox Be Done Here?”

Botox in a dental office should not be interesting merely because a dentist is holding the syringe.

The more meaningful question is:

What perspective does the dentist bring to the treatment?

For me, that perspective comes from decades spent studying smiles, facial relationships, dental function, muscle activity, symmetry, proportion, and the enormous difference that subtle changes can make.

Botox is another tool. It is not the treatment philosophy.

My philosophy is to understand the patient’s concern, respect the anatomy, preserve natural expression, use treatment conservatively, and recognize when doing less will produce the better result.

“The goal of facial aesthetics shouldn’t be to erase the evidence that you’ve lived or make everyone look the same. It should be to create balance while allowing you to continue looking unmistakably like yourself.”
