How Much Does Teeth Bonding Costs?

If you have gound down your teeth, the soft plastic material used in bonding won't withstand the wear and tear that you generate. You would need a porcelain, metal or combination of the two to restore your teeth. This is a very complex process and most dentists will shy away from this level of care. This is often called a full mouth reconstruction, or sometimes just half (perhaps just the uppers) can be done.
Unless your worn teeth are only slightly worn, you should plan on a large investment. Usually fees for this run in the $20,000 to $50,000 range and can go up from there depending on complexity.

Fees generally vary depending on the expertise and skill of the clinician, and what needs to be done prior to bonding.  They can be anywhere between $100 - $1,500 per tooth.  Any dentist can bond your teeth, you want to make sure you select one who will take a comprehensive approach.  If you jump directly to bonding without planning properly, you may find yourself visiting your dentist frequently to repair or replace the bonding and spending more money in the long run.  If there is significant wear, your teeth may have supraerupted or drifted out/down in which case there may be limited space to add material.  If that's the case, it can be corrected with Orthodontics - moving the teeth back where they belong, or Periodontics - in which the gums could be moved up with various gum procedures.  Another possibility may be to add bonding farther back to multiple teeth in order to built height and create more space in the front.  You may also ultimately need a nightguard for grinding to protect the bonding, and to get screened for potential airway/sleep disordered breathing which has shown correlations with grinding.  Finally, I would recommend a waxup or prototype with comprehensive diagnostic records before committing to treatment in order to see the esthetic result, and what can be done to achieve a durable and predictable outcome.  

At any cost....Attempting to repair WORN DOWN FRONT TEETH with any material at all before addressing the UNDERLYING PROBLEMS will leave you very disappointed when you continue to break it off. In all likelihood you have other issues that can range from bite problems to airway issues and more. It is not a simple fix. If you don't want to keep redoing the dentistry over and over find a dentist that can help you get to the bottom of what is really going on.
