Dental bonding is the application of a durable composite resin (plastic) which is expertly color-matched to your teeth. This dental bonding material has the consistency of soft putty before it is cured so it easily fills gaps and spaces. Once applied, the resin is cured with a special ultraviolet light. The light both hardens and bonds the resin material to your teeth. It is then further trimmed down, shaped, and polished to blend flawlessly with the translucence and reflectivity of the remaining tooth. In the end, no one can tell where the tooth ends and resin begins. It just looks like a normal tooth.
Normally used for smaller problem areas, the entire dental bonding procedure can be completed in a single visit. That makes it ideal for the correction of many dental issues including,
- cavities in front teeth
- to fill in corrosion or decay at the root level
- chipped or cracked teeth
- discolored teeth
- gaps between teeth
- to elongate teeth
- change tooth shape
- replace metal fillings
Unless the bonding is being used to fill a cavity, anesthesia may not even be needed since the procedure is painless. Dental bonding is super fast, often requiring as little as 30 to 60 minutes and is among the least expensive of cosmetic dentistry techniques.
First, the colors of resin and tooth are matched using an enamel shade guide. Then the surface of the tooth will be roughened up a little and a conditioning liquid applied to help the material bond at a molecular level.
No special care is required for a tooth that has been repaired with dental bonding, just normal flossing and brushing twice a day. Dental bonding is stain resistant, but not stain proof. So normal oral hygiene practices will keep them looking great.
Though not as strong as porcelain veneers or crowns, dental bonding normally works well on front teeth especially because bite pressure is low. However if you bite your nails or chew objects like pencils or pens, or use your front teeth to open packages or bottles, you may chip or break the dental bonding material. If this ever happens the tooth will feel rough or sharp and you will have to return to the dentist for a touch up. Otherwise dental bonding can last up to 10 years before needing to be replaced.
