Multiple sclerosis (MS) is a chronic condition affecting the central nervous system. While it is best known for symptoms such as fatigue, muscle weakness, numbness, balance difficulties, and changes in coordination, MS can also make maintaining oral health more challenging.

The disease does not automatically cause tooth decay or gum disease. However, changes in movement, sensation, saliva flow, swallowing, facial pain, and medication use can make daily oral hygiene and professional dental treatment more difficult. Research reviews have found associations between MS and several oral health concerns, particularly dry mouth, periodontal disease, temporomandibular disorders, altered facial sensation, and trigeminal neuralgia.

At her Henderson, Nevada practice, Marielaina Perrone, DDS, believes patients living with MS deserve dental care that is flexible, respectful, and adapted to their individual symptoms. With thoughtful planning and preventive care, most people with multiple sclerosis can maintain healthy teeth and gums for life.

What Is Multiple Sclerosis?

Multiple sclerosis is an immune-mediated disease in which inflammation damages myelin, the protective covering surrounding nerve fibers in the brain, spinal cord, and optic nerves.

Because the nervous system helps control movement, sensation, vision, speech, and coordination, MS symptoms vary widely from one person to another. Symptoms may also change over time, with periods of stability, progression, or temporary flare-ups.

Common symptoms include:

• Fatigue
• Muscle weakness or stiffness
• Numbness and tingling
• Tremors
• Balance or coordination difficulties
• Vision changes
• Cognitive changes
• Facial pain
• Difficulty swallowing

These symptoms can influence both home oral care and the dental appointment itself.

Dr. Perrone’s Perspective

“Multiple sclerosis affects every patient differently, so dental care should never follow a one-size-fits-all approach. The most important first step is listening—understanding the patient’s symptoms, medications, energy level, and concerns so treatment can be made as comfortable and predictable as possible.”

How Can Multiple Sclerosis Affect Oral Health?

MS may affect oral health directly through neurological symptoms or indirectly by making everyday dental care harder.

Difficulty Brushing and Flossing

Weakness, tremors, muscle stiffness, numbness, or reduced hand coordination may make it difficult to:

• Hold a toothbrush
• Reach every tooth surface
• Control floss
• Brush for a full two minutes
• Remove plaque consistently

When plaque remains along the gumline, the risk of cavities, gingivitis, and periodontal disease increases.

This is not a reflection of poor motivation. It is often a practical consequence of changes in motor control.

Dry Mouth

Dry mouth, or xerostomia, may result from medications, dehydration, mouth breathing, or changes in salivary function. Recent evidence identifies oral dryness as one of the more consistent oral concerns reported in people with MS.

Saliva protects the mouth by:

• Washing away food particles
• Neutralizing acids
• Limiting bacterial growth
• Supporting swallowing
• Protecting tooth enamel

Reduced saliva may increase the risk of:

• Cavities
• Root decay
• Gum inflammation
• Bad breath
• Oral yeast infections
• Difficulty chewing and swallowing
• Burning or irritated oral tissues

Gum Disease

Research suggests that people with MS may experience poorer periodontal health than those without MS, although the relationship is complex and does not prove that one condition directly causes the other. A 2023 meta-analysis involving 3,376 individuals reported that patients with MS were more likely to have chronic periodontitis than healthy controls.

Possible contributing factors include:

• Difficulty performing daily oral hygiene
• Dry mouth
• Smoking
• Medication effects
• Reduced access to dental care
• Chronic inflammation
• Physical disability

Recent research continues to investigate how periodontal inflammation and changes in the oral microbiome may relate to systemic immune activity in MS, but causation has not been established.

Trigeminal Neuralgia and Facial Pain

Trigeminal neuralgia causes sudden, intense, electric-shock-like facial pain. It may affect the jaw, cheeks, teeth, lips, or gums and can sometimes be mistaken for a dental problem.

Multiple sclerosis is a recognized cause of secondary trigeminal neuralgia because MS-related nerve damage may affect the trigeminal nerve.

Pain may be triggered by:

• Touching the face
• Brushing the teeth
• Chewing
• Speaking
• Cold air
• Washing the face

Because trigeminal neuralgia can resemble toothache, careful diagnosis is critical before irreversible dental treatment is performed. Orofacial pain and altered sensation are among the recognized dental considerations in patients with MS.

Numbness, Tingling, and Altered Sensation

MS may cause altered sensations in the lips, tongue, face, or oral tissues.

Patients may describe:

• Tingling
• Burning
• Numbness
• Pins-and-needles sensations
• Unexplained oral discomfort
• Changes in temperature perception

These symptoms should be evaluated carefully because they may be neurological, dental, medication-related, or caused by another oral condition.

Jaw Pain and Temporomandibular Disorders

People with MS may experience increased jaw tension, muscle fatigue, clenching, or temporomandibular joint discomfort.

A systematic review found evidence of an association between MS and temporomandibular disorders, and more recent meta-analysis has likewise reported a higher prevalence of TMD among people with MS.

Symptoms may include:

• Jaw soreness
• Clicking or popping
• Facial muscle fatigue
• Headaches
• Difficulty opening the mouth
• Pain while chewing

Treatment depends on the cause and may include conservative therapies such as a custom nightguard, dietary modification, muscle relaxation strategies, or coordination with the patient’s physician.

Swallowing Difficulties

Some people with MS develop dysphagia, or difficulty swallowing.

This may affect:

• Saliva control
• Eating
• Drinking
• Taking medications
• Tolerance of reclining in the dental chair

Patients should tell their dentist about swallowing concerns before treatment. The chair position, suction, appointment length, and use of dental materials can then be adjusted for greater comfort and safety.

Medication Considerations

Medications used to manage MS symptoms or disease activity may affect oral health and dental treatment.

Potential concerns include:

• Dry mouth
• Altered taste
• Increased infection susceptibility
• Delayed healing
• Oral ulceration
• Medication interactions
• Fatigue or dizziness
• Changes in bleeding risk

Some anti-CD20 therapies used in autoimmune disease management have been associated with reported dental problems, including tooth pain, caries, abscesses, fractures, periodontitis, and tooth loss, although the available evidence does not prove that the medications directly caused every reported condition.

Bring an updated medication list to every dental appointment, including:

• Prescription medications
• Infusion therapies
• Steroids
• Muscle relaxants
• Pain medications
• Supplements
• Over-the-counter products

Never stop or change an MS medication without consulting the prescribing physician.

How Dental Appointments Can Be Made More Comfortable

Small adjustments can make a major difference.

Schedule Around Your Best Time of Day

Fatigue is one of the most common MS symptoms.

Many patients benefit from:

• Morning appointments
• Shorter visits
• Scheduled rest breaks
• Avoiding appointments immediately after demanding activities

Treatment should ideally be scheduled during periods when symptoms are stable rather than during an active relapse whenever possible.

Keep the Dental Office Comfortable

Some people with MS are sensitive to heat and may notice worsening symptoms when they become overheated.

A cooler treatment room, lightweight blanket, and access to water may improve comfort.

Allow Extra Time for Position Changes

Patients with stiffness, weakness, dizziness, or balance concerns may need additional time when:

• Entering the chair
• Reclining
• Sitting upright
• Standing after treatment

Rushing these transitions may increase discomfort or fall risk.

Use Supportive Positioning

Neck, back, or limb support may reduce muscle fatigue.

Pillows or positioning aids can help patients remain comfortable during longer procedures.

Establish a Stop Signal

A simple hand signal allows the patient to pause treatment at any time.

This can be especially helpful for individuals experiencing:

• Muscle spasms
• Facial pain
• Swallowing difficulties
• Anxiety
• Fatigue

Making Home Oral Care Easier

Adaptive tools can help patients maintain independence.

Consider:

An Electric Toothbrush

A powered toothbrush requires less hand movement and may improve plaque removal for patients with reduced strength or coordination.

Choose a model with:

• A large handle
• Lightweight design
• Two-minute timer
• Pressure sensor

A Larger Grip

A toothbrush handle can be enlarged using:

• A bicycle grip
• Foam tubing
• A tennis ball
• A commercially available adaptive handle

A larger surface is often easier to hold.

Water Flossers and Interdental Brushes

Traditional string floss may be difficult to control.

Alternatives include:

• Water flossers
• Floss holders
• Interdental brushes
• Soft rubber cleaners

Dr. Perrone or the dental hygienist can recommend the most suitable option.

Seated Oral Hygiene

Brushing while seated may reduce fatigue and improve balance.

Patients can also rest their elbow on the counter for greater stability.

Caregiver Assistance

When symptoms significantly affect mobility or cognition, a family member or caregiver may need to assist with oral hygiene.

Caregiver education is an important part of preventing cavities, periodontal disease, and oral infection when independent home care becomes difficult.

Managing Dry Mouth

Helpful strategies may include:

• Drinking water frequently
• Using sugar-free gum or lozenges when safe
• Avoiding tobacco
• Limiting alcohol
• Reducing excessive caffeine
• Using a humidifier
• Choosing alcohol-free mouth rinses
• Using saliva substitutes when recommended
• Receiving professional fluoride treatments
• Using prescription-strength fluoride toothpaste when appropriate

Persistent dry mouth should be discussed with both the dentist and physician.

Preventive Dental Care Is Especially Important

Patients with MS may benefit from a more individualized preventive schedule based on:

• Gum health
• Cavity risk
• Dry mouth
• Ability to perform home care
• Medication use
• Previous dental disease

Preventive care may include:

• Professional cleanings
• Periodontal evaluations
• Fluoride treatments
• Dry-mouth management
• Nightguard therapy
• More frequent recall visits
• Nutritional counseling
• Early restorative care

Preventing dental disease is usually easier than managing extensive treatment later, particularly when mobility or fatigue becomes more limiting.

Can People With MS Receive Dental Implants?

Multiple sclerosis does not automatically prevent implant treatment.

Candidacy depends on:

• Overall health
• Gum health
• Bone quality
• Oral hygiene
• Smoking status
• Medication history
• Ability to attend maintenance visits
• Capacity to clean around the implants

Published evidence remains limited, so implant treatment should be individualized and coordinated with medical providers when appropriate. Recent reviews and case reports emphasize comprehensive risk assessment, interdisciplinary planning, and strict long-term maintenance.

Frequently Asked Questions

Does multiple sclerosis cause cavities?

MS does not directly cause cavities. However, dry mouth, medication effects, fatigue, limited dexterity, and difficulty performing home care may increase cavity risk.

Are people with MS more likely to develop gum disease?

Research suggests an association between MS and poorer periodontal health, but it has not established that MS directly causes gum disease. Home care limitations, dry mouth, smoking, inflammation, and access to care may all contribute.

Can MS cause tooth pain?

MS may cause trigeminal neuralgia or altered facial sensation that feels like dental pain. A complete dental evaluation is essential before assuming the discomfort is neurological.

Is dental anesthesia safe for patients with MS?

Local dental anesthesia is generally usable for patients with MS, but treatment should be planned around the individual’s medical history, symptoms, allergies, and medications.

Should dental treatment be avoided during an MS relapse?

Elective treatment may be postponed during a significant relapse if symptoms interfere with comfort or safety. Urgent dental infections still require prompt evaluation and coordinated care.

How often should someone with MS see the dentist?

Most patients should have at least routine examinations and professional cleanings every six months. Those with dry mouth, periodontal disease, frequent cavities, or difficulty performing home care may need visits every three to four months.

Can a dentist help with MS-related dry mouth?

Yes. A dentist can recommend fluoride protection, saliva substitutes, dietary changes, home-care products, and a more frequent preventive schedule.
