I have anxiety and cannot be numbed up. For the most part my bonding is still very much in tact. I would just like it touched up if possible to whiten my front teeth. Is this possible to do without having to drill out the teeth and start over again? Any opinions on whiteners like Supersmile that are supposed to whiten these dental bonds?

Retouching old bonding
While not the ideal way to do it, it is possible to add to old composite bonding material. If the areas to be
retouched aren't too extensive, it's also possible to do it comfortably without being numb. I would want to roughen the old bonding surface first though, and that means using a drill at least a little. This is done to get the best bond of new material to old. Composite filling material (bonding) can often extend further and deeper than it appears, so changing large areas could become uncomfortable without anesthetic. It depends on how much bonding was originally done. As for whiteners, they really only work well on tooth structure, not bonding.
Retouching discolored bonding
Older bonding materials were notorious for discoloring over time. Modern composite bonding materials are far more color stable and resist staining than the older tooth colored materials. If the material itself has discolored and there is no evidence of recurrent decay then simply abrading and polishing the surface of the filling may return the resoration to it's original appearance. If an x-ray reveals decay under or around the filling or a dark line or opening is seen along the outer edges of the filling, then replacement is necessary. Toothpastes and whitening products have little to no effect on tooth colored restorations. Products which are abrasive enough to remove stains from fillings are far more damaging to natural tooth enamel. I have found that patients hesitant to have the old restoration "drilled out" are usually anxious about having a painful experience. Ask your dentist which method of anesthesia is best for your level of anxiety, not all methods require a "shot".
SuperSmile Toothpaste is great for maintenance care.
Great question about re- bonding to old composite. It is always challenging. The main reason is that the old composites are saturated with saliva. To re-bond you need non contaminated enamel. Sometimes you can do a little spot and need a sand blaster to remove the outer layer. My experience has been that removing the old composite and providing a clean surface guarantees a great result that will last.
I suggest having the bonding polished professionally and use Supersmile Toothpaste to see how the bonding looks. Decide why you need to rebond-for better color? for stain? for fit? Then make your decision based on the facts. Bonding is reliable and a great conservative solution to many dental issues. Good luck!! Dr. Wendy Spektor

You can touch up or repair old bonding.
Depending on the condition and amount of unsightly, damaged, or discolored bonding, you can repair most bonding if it had looked good to begin with. It normally can be done comfortably without the need for anesthesia. No tooth structure need be removed/ prepared in the process. If the problem is mainly discoloration some of the discolored surface material should be removed. Unless the discoloration is due to surface stains then whitening will generally not work.
Touching up Bonding
Bonding material will absorb color and stain or darken over the years. If the color is still pleasing to you, then bonding can be touched up to repair areas of wear. However, bonding cannot be bleached out or whitened with toothpastes or even professional whitening systems.
If they had to numb you the first time to do your bonding, then I am assuming the dentist removed some enamel off the front of your teeth. This is sometimes needed in a small percentage of situations. More commonly, bonding is done without numbing.
Touch up old bonding
If the stains are very superficial they may be able to be removed with polishing burs/discs. This could give some new life to the bonding.
If the stains are deeper or show on the margins you may be able to patch them up with minimal prepping but the issue may be a difference in the material that was used years ago to what is used now. Different types of composite (the material used in bonding) have different properties and that is especially true with old versus new composite filling material. So while there can be a "best match" the difference in the materials may not allow this to blend perfectly.
If you elect to have the bonding completely replaced, if the enamel was not or minimally removed during the original bonding then there should be minimal sensitivity during the procedure. If the underlying tooth (dentin) is exposed, you could have significant sensitivity or discomfort.
Discolored old bonding
A few things to consider: How did you have your teeth bonded the first time? How old is the original bonding? What are your habits (coffee, tea, red wine, tobacco use, etc)? Have you tried or considered some sort of sedation option (nitrous oxide, happy pills, IV sedation)? Assuming there are no underlying issues with the teeth (sensitivity, decay, open margins, etc), and that this is purely a color issue, the bonding can, in most cases, be re-surfaced without the use of any anesthetic to brighten your smile. Look for a highly skilled cosmetic dentist to help you achieve your dental goals.
No Drills Bonding
It's better to replace an old discolored bonding instead of patching it up. New bonding material should be placed on a clean service to get better lasting results. You want to make sure that x-rays are taken to make sure there is no decay under bonding material if you decide not to have bonding material completely removed. Whitening solutions only work on natural teeth, as far as your anxiety you might want to ask your dentist if he can prescribe something to help or if he can give you nitrous, you want to make sure you let Dr. know if you have any allergies to any medication or any health problems so he can prescribe the right medication.
Touching up Dental Bonds that are intact but not as white as they should be
Dental bonding is a simple and price effective method for making teeth nice and even and white without the pan and expense of veneers. If your dental bonding is pretty much intact, and you are happy with it, I would suggest that you ask your dentist to redo the bonding and make it look whiter, and smoother and cosmetically appealing . This type of process can be easily be changed up and added to, correcting the shade and the contour of the teeth. If you have anxiety and fear using an anesthetic, I would suggest you have them rebonded. It is fast, inexpensive and no pain is involved! Hope this helps! Good luck!
