What is the purpose of dental bonding?

Dental bonding is a cosmetic dental procedure that involves the application of a tooth-coloured resin material to repair or improve the appearance of a tooth. The purpose of dental bonding includes:

  1. Repairing Tooth Decay: Dental bonding can be used to fill cavities and repair tooth decay. The resin material is colour-matched to the natural teeth, providing a more aesthetically pleasing result compared to traditional silver amalgam fillings.
  2. Restoring Chipped or Cracked Teeth: Bonding is often used to repair minor chips or cracks in teeth. The resin is applied to the damaged area, shaped to match the natural tooth contours, and then hardened with a special light, restoring the tooth's appearance and function.
  3. Closing Gaps Between Teeth: Dental bonding can be used to close small gaps or spaces between teeth, providing a quick and non-invasive alternative to orthodontic treatments like braces or aligners.
  4. Improving Tooth Shape and Size: Dentists use bonding to reshape or resize teeth, enhancing their overall appearance. This can be particularly useful for teeth that are misshapen or smaller than adjacent teeth.
  5. Covering Discolorations: Dental bonding can be applied to teeth with discolorations or stains that do not respond well to traditional teeth whitening methods. The resin is matched to the natural tooth colour, creating a more uniform and attractive smile.
  6. Protecting Exposed Tooth Roots: In cases where tooth roots become exposed due to gum recession, bonding can be applied to cover and protect the exposed area, preventing sensitivity and further damage.
  7. Cosmetic Smile Makeovers: Dental bonding is often a part of cosmetic smile makeovers, helping to create a more harmonious and aesthetically pleasing smile by addressing various imperfections in the teeth.


The lifespan of dental bonding can vary depending on several factors, including the location of the bonding in the mouth, the patient's oral hygiene practices, dietary habits, and the overall wear and tear the bonded teeth experience. On average, dental bonding can last anywhere from 3 to 10 years or more. Here are some factors that can influence the longevity of dental bonding:

  1. Location: Bonding on front teeth may be subjected to more biting forces and aesthetic demands, potentially impacting its durability compared to bonding on back teeth.
  2. Oral Hygiene: Good oral hygiene practices, including regular brushing, flossing, and professional dental cleanings, can contribute to the longevity of dental bonding. Poor oral hygiene may lead to decay or staining around the bonded area.
  3. Dietary Habits: Avoiding hard or sticky foods and refraining from habits like biting on ice or using teeth as tools can help prevent damage to the bonded material.
  4. Teeth Grinding (Bruxism): Individuals who grind or clench their teeth may experience wear and damage to dental bonding over time. A nightguard or other protective measures may be recommended in such cases.
  5. Smoking and Staining Substances: Smoking and consuming staining substances like coffee, tea, or red wine can discolour the bonding material over time, affecting its appearance.
  6. Regular Dental Check-ups: Regular dental examinations allow the dentist to monitor the condition of the bonding and address any issues early on, potentially extending its lifespan through prompt maintenance or repairs.


The cost of dental bonding and veneers can vary based on several factors, including the materials used, the location of the dental practice, the complexity of the case, and the dentist's experience. Generally, dental bonding is a more cost-effective option compared to veneers. Here's a brief comparison:

  1. Dental Bonding:
    • Cost Range: The cost of dental bonding typically ranges from $100 to $400 per tooth, but this can vary based on the factors mentioned above.
    • Material: Dental bonding involves the application of a tooth-colored resin directly to the tooth. It is a more affordable option because it can be done in a single visit, and the materials are less expensive compared to those used for veneers.
  2. Dental Veneers:
    • Cost Range: The cost of veneers is generally higher than dental bonding. Veneers can range from $500 to $2,500 or more per tooth, depending on the type of veneer (porcelain or composite), the complexity of the case, and other factors.
    • Material: Porcelain veneers, in particular, are more expensive than composite veneers. Porcelain veneers are custom-made in a dental laboratory and usually require more than one dental visit for preparation and placement. They are known for their durability and natural appearance.

While dental bonding is a more affordable option, veneers offer certain advantages, including greater durability and resistance to staining. Veneers can also provide a more significant transformation for individuals with more complex cosmetic concerns, such as severely stained or misshapen teeth.

It's important to consult with a dentist to determine the most suitable option based on individual needs, cosmetic goals, and budget considerations. Additionally, dental insurance may not always cover the cost of cosmetic procedures like bonding or veneers, so patients should inquire about payment plans and financing options if needed.


Dental insurance coverage for dental bonding can vary depending on the specific insurance plan and the reasons for seeking the procedure. In general, dental insurance is more likely to cover procedures that are considered necessary for dental health rather than purely cosmetic treatments.

Here are some factors to consider:

  1. Functional Purpose: If dental bonding is needed for functional reasons, such as to repair a decayed or damaged tooth, there's a higher chance that dental insurance may cover it. In such cases, dental bonding may be considered a restorative procedure.
  2. Cosmetic Purpose: If the primary purpose of dental bonding is cosmetic, such as improving the appearance of teeth by closing gaps or covering minor imperfections, it is less likely to be covered by dental insurance. Many dental insurance plans do not cover purely cosmetic procedures.
  3. Preauthorization: It's essential to check with the dental insurance provider before undergoing any procedure. Some insurance plans require preauthorization or documentation from the dentist to determine if the treatment is medically necessary.
  4. Alternative Procedures: Dental insurance may cover alternative procedures that serve the same functional purpose as dental bonding. For example, if bonding is being considered to address decay, insurance may cover a filling or another restorative option.
  5. Plan Limitations: Even if dental insurance covers dental bonding for certain situations, there may be limitations on the coverage amount or the number of times the procedure can be done within a specific time frame.
  6. Patients should contact their dental insurance provider to inquire about coverage for dental bonding and to understand the terms and conditions of their specific plan. Additionally, discussing the proposed treatment plan with the dentist and obtaining any necessary documentation for insurance purposes can help facilitate the reimbursement process. Keep in mind that cosmetic procedures are generally less likely to be covered, and patients may need to explore other payment options for such treatments.


While dental bonding is a relatively durable and cost-effective cosmetic solution, it may not be as long-lasting as certain alternatives like dental veneers or crowns. If the bonding begins to chip, crack, or discolour, it may need to be repaired or replaced. Individuals with dental bonding need to maintain good oral hygiene, follow their dentist's recommendations, and attend regular dental check-ups to ensure the longevity of the bonding and overall oral health.
