Dental emergencies seem to arise at the most inconvenient times. Some dental emergencies are serious while others are inconveniences at best. Anyone who has had a temporary crown or a permanent dental crown/onlay/porcelain veneer should be aware that it could eventually come off. They may be able to be placed back on, or may need to be completely replaced…But why does it happen?

How Do Dental Crowns Stay On Your Teeth?

Dental crowns are placed over your prepared tooth using a special adhesive cement. This cement has the ability to bond to both your natural tooth structure as well as the inner lining of the dental crown. Depending on the type of dental crown your dentist will use a different type of cement. The shape of the tooth is also important in keeping the crown on. The tooth is prepared by the dentist to be “retentive”, meaning that the shaping of the tooth itself helps to keep the crown on as well.

Why Would My Dental Crown Come Off?

-Tooth Decay. A tooth that has a dental crown needs to be kept clean through brushing, flossing and rinsing. Tooth decay can still occur at the margins of the dental crown, (where the crown edge ends and the tooth begins)  and eventually make their way up and under the dental crown. If tooth decay does occur under a crown, it may need a new crown to be fabricated or if the tooth decay progresses far enough a root canal may be needed to salvage the tooth.

-Sticky, Chewy Foods. This can occur from continual use or just one time chewing a sticky piece of candy. Generally, over time these sticky, chewy foods can slowly break the cement seal and work a dental crown loose. If it is just pulled off from a candy, your dentist will examine both the tooth and the crown to ensure there is no tooth decay or damage to the tooth or crown. If all is well, your dentist may be able to simply recement the crown and you will be on your way.

-Crown Damage. A dental crown is a man made tooth shell that is capable of fracturing or breaking over time. Our teeth absorb extreme amounts of force on a daily basis. The metal or porcelain on a crown can wear through, chip, or fracture.

-Oral Habits. Yes, our habits can effect the longevity of a dental crown. Bad habits include teeth grinding (bruxism), clenching, nail biting, ice chewing, using teeth to open packages and bottles, chewing on pens, etc.. These forces will break porcelain, wear metal, and stress the adhesive bond causing the dental crown to loosen over time,.

-Small/Short Teeth. This can usually be overcome by your dentist “building” your tooth back up with dental resins but in some instances all of  the teeth are shorter due to teeth grinding. The shortness is directly related to a decrease in retentiveness. This creates an issue over time, as the crown adhesive is working doubly hard to maintain its place on the tooth.

-Cement Breakdown. This can occur when the margin seal is broken causing the cement to leak out, or if a small amount of blood or saliva gets under the dental crown while cementing. If there is any moisture (saliva or blood) on the tooth upon cementation this can cause a weaker bond to develop for the cement. This will lead to a loosening of the crown over time. Simple fix in most cases is to just recement the dental crown back on either using a different cement or ensuring the area is clean and dry.

-Poor Fit. Sometimes a tooth is not prepared ideally, an impression of the tooth is distorted, the lab creates a poor fit to the tooth, or it is not completely seated on the tooth during cementation. When these issues occur, leakage of bacteria and saliva occur under the crown and loosen it.

Conclusion

As mentioned earlier, a dental crown coming off is a routine dental emergency but usually not a painful one. In many cases (if the dentist is unavailable), the patients try to temporarily recement their dental crown back on using fixodent (denture adhesive), toothpaste, or temporary dental cement from the local drug store. The best course of action is to see your dentist as soon as you can to ensure you do not experience any discomfort, do not swallow the dental crown, or permanently damage the tooth or crown.

Many of us see a beautiful smile and wish that it could be ours. Few of us are born with perfectly shaped, straight, white teeth. In the past, “natural smiles” were the norm, but today, cosmetic dentistry has evolved to offer many corrective options. This has allowed many patients to take advantage of these modern options to give them that “perfect smile” they have always dreamed about. What about those patients who choose not to go that extra step for that perfect smile?

What Is Snap On Smile?

Snap on smile is a revolutionary solution for many cosmetic dental issues. The beauty of the snap on smile is that it is a totally reversible cosmetic dentistry option. The snap on smile is much more affordable than porcelain veneers or porcelain crowns. In general, the snap on smile procedure costs as much as a single porcelain crown.

Snap on smile is a removable arch of “teeth” which is designed to snap over the existing teeth. The snap on smile removable appliance is made from an extremely strong dental resin. It can be used as a short term or a long term cosmetic dentistry option. The following are the steps involved in the fabrication of a custom snap on smile:

-Dental Impressions. This will include impressions of the teeth, photographs, along with a bite registration. A bite registration allows the dental lab to know the relationship between the upper and lower teeth. At this visit you and your dentist will also pick out the style, shape, and color of your new smile.

-Dental Laboratory. The information gathered by the dentist is then sent off to the dental laboratory. The dental technician will digitally create the custom made snap on smile.

-Snap On Smile Insertion. Following fabrication by the lab technician, your dentist will then place the final product over your teeth. The snap on smile pops right in over your own teeth and fits perfectly.

The snap on smile is so simple to complete without the need for removing any of your natural tooth structure or need to use any anesthesia. The beauty is that it is completely removable at any time with no effect to your natural teeth.

Common Snap On Smile Questions

-Will Snap On Smile Affect My Speech? It usually takes about 2 weeks to get used to the new teeth and speak as yo did before.

-Is It Covered By My Dental Insurance? Snap on smile is considered a cosmetic procedure and is therefore not covered by dental insurance.

-Will It Stain? Your dentist will supply you with special snap on smile cleaning supplies. This kit includes a cleaning solution and an antibacterial gel. Using this kit regularly will help keep your new smile looking like new.

-How Long Does It Take? The entire process can be completed in as little as 3 weeks. The initial appointment (includes photos and impressions) should take 15-20 minutes. The laboratory needs about 2 weeks to complete fabricating your new snap on smile. And the final appointment is a short one ensuring proper fit and comfort.

-Is There A Warranty? There is a 1 year warranty, but an extended warranty can be purchased.

-Can I Cover All Of My Teeth? Upper and lower snap on smiles are available, however most people choose to do the upper only.

-Can I Eat And Drink While Wearing My Snap On Smile? Yes, your new smile is designed to wear during eating and drinking. However, be aware your new smile can stain just like your real teeth if not cleaned properly.

Many of us choose haircuts or clothes based on our facial or body shape so why not our teeth? We are all born with a set of teeth that may or may not be perfect to us. There may be minor flaws or major ones to our eyes. With modern cosmetic dentistry, teeth changes can be made to improve your overall appearance and look very natural.

Cosmetic Dentistry Can Change Your Smile!

Facial Analysis and Cosmetic Dentistry To Transform Your Smile

It is essential for your dentist to do a facial analysis in treatment planning for cosmetic dentistry. The face drives the shape and position of the teeth. If someone smiles at you and it’s a high and wide smile, the teeth might be out of balance or out of proportion to the face. If this is the case, the smile needs to be altered to bring about balance and proportion.

Simply put, the face, mouth, and lips direct the size of the teeth. The facial aesthetic drives the tooth size and position. Your dentist will need to look at the face from both the front and the side, the relationship between the lips and the teeth and the teeth’s shape, color, size and position.

“There is an important harmony that exists between teeth and facial features for a successful cosmetic dentistry result.”

The shape of the head, size and position of the eyes, nose, lips, cheekbones all play a role in determining the size, position, shape and contour of the teeth. Your cosmetic dentist should do a complete analysis with models of your mouth and records may include extra oral photographs of the full face, profile, smile and intra oral photos of the teeth, bite, gums, and arch form, and measurements. The architecture of the mouth, including the patient’s lip line (e.g., a high lip line give a “gummy smile” appearance), and gum line contours are an integral part of facial analysis.

Cosmetic dentistry utilizes many procedures to make the changes necessary to make your smile complement your face. The goal in cosmetic dentistry is to create a natural looking smile, so that only the dentist and patient know what was done. This becomes especially important as we age. Listed below are some of the cosmetic dentistry procedures that can be used to make complementary changes:

Cosmetic Dentistry Marielaina Perrone DDS-Dental BondingDental bonding is the process in which tooth colored dental materials are bonded to a tooth. This might be one of the easiest cosmetic dentistry procedures to change our look. Using dental bonding we can change shape, size, color, length, and close any spaces that might be present. Dental bonding is generally completed in the dentist office in as little as an hour. The main drawbacks of dental bonding are chipping, wearing, and staining. The final product is not as strong as a porcelain restoration and may need to be updated over time, but can be done in less time for less money. While dental bonding is also used to restore teeth damaged by tooth decay it can also be used as a cosmetic veneer. This procedure can easily alter your smile in as little as an hour, and is minimally invasive. Dental bonding is a very easy way to make your smile youthful looking again.

-Porcelain Veneers and Porcelain Crowns. Often referred to as “instant orthodontics”, porcelain veneers can change the alignment of teeth, if the alignment issues are not too extreme. Porcelain veneers and porcelain crowns can be a great way to replace lost tooth structure and alter imperfect teeth creating a more youthful appearance. These cosmetic dentistry procedures tend to require more than one visit, but the results will give you a beautiful, youthful smile that lasts. Porcelain Veneers are custom made, ultra thin, tooth colored shells that are adhesively bonded to the teeth, and do not change color over time. This allows the cosmetic dentist to not only alter color of your teeth, but shape and lengthen as well. Porcelain crowns can be used on teeth that either already have crowns or need more extensive work (having large restorations or tooth decay). Both porcelain veneers and porcelain crowns can as used in cosmetic dentistry to give the patient a flawless, more youthful and attractive smile.

Tooth Shapes To Complement Your Face Type

A good cosmetic dentist will note all factors during treatment planning. Individual facial type is one of those important factors in cosmetic dentistry. The following is a guide to different facial shapes and their complementary teeth shapes:

-Small Face: A small face requires smaller porcelain veneers or porcelain crowns. Long, square shaped tooth shapes should be avoided. If the teeth are too long it will notCosmetic Dentistry Marielaina Perrone DDS be in line with overall proportions of your face.

-Angular or Square Shaped Face: For this type of face softer edges are required. This will help soften the overall smile and merge it better with the rest of your face. Sharp angled teeth may be too harsh of a look.

-Fuller Face: Just like vertical stripes make a person look slimmer, slightly longer teeth can create a slimming effect.

-Thin Face: The key here is to avoid thin, long teeth. They will only make your face appear longer. Wider, fuller teeth will broaden your smile and add fullness to your smile.

Other factors to consider:

-Tooth color - Lighter teeth are what most of us desire when altering cosmetics. Keep in mind, that skin color, lip color, and hair color effect how whit your teeth appear. You, and your dentist should go through several options to see what will work best for you.

-Tooth size - As we age our teeth tend to shift, chip, and wear. Tooth size and shape consequently change. Restoring back to proper proportions make your teeth appear healthier and more youthful.
