Can bonding wear off in a month or less?

Photos are always helpful, but which part of the tooth was the yellow stain and "scratchy" look/feel located?  Was it the edge/tip of the tooth, middle, or near the gum?  If on the edge, most likely it was chipped off.  If it was in the middle or towards the gum, there may have been a technical error or missed step in the adhesion process, or perhaps it was the actual quality of the composite material used.  There might also be an underlying issue such as a tooth grinding habit, toothbrush or toothpaste abrasion (overagressive brushing and/or abrasive toothpaste), intrinsic acid erosion (acid reflux) or extrinsic acid erosion which can come from acidic foods and liquids such as lemons, sodas and juices.  Acid is highly detrimental to enamel and it can also negatively impact composite bonding.  If you're looking for predictability and longevity, proper planning is paramount.  I would highly suggest x-rays with a complete exam, and to have your dentist fabricate a diagnostic wax-up prototype with a laboratory technician which will show what outcome is possible, and what will be necessary to achieve that outcome and to last a long time.  If more dentistry is necessary to accomplish your goals, just know you always have different options and alternatives to phase and spread out treatment in order to make it affordable.  Otherwise you may be paying your dentist a visit every 2 weeks for repairs and patchwork, and ultimately a much higher cost than you anticipated.  Hope this helps, good luck!

You neglected to mention if you just had bonded fillings or direct composite veneering?In general properly done bonding with the cosmetic dentist using state-of-the-art composite resin restorations will not wear off in a month or less. However, something to keep in mind, your tooth is the hardest part of the human body, and it wears down over the years. Composite bonding can be compared to a type of plastic, which will wear over time. In your case, the important thing to find out is whether it is happening to you because of the material the dentist used, his technique, or do you have some other factors going on that is causing the accelerated wear. This might include using an abrasive tooth paste and hard brushing. Or, biting on hard foods. Possibly the acid in your diet (to you have GERD..gastroesophageal reflux disease)? Abrasion, attrition or erosion of your bonding?If your bonding is so short lived, then you might consider using porcelain veneers to solve the problem.

At the simplest level direct composite bonding is a technique sensitive procedure that if done incorrectly will not have a long term stability both functionally and aesthetically. It can chip and stain quite easily.

if Cosmetic Bonding is not treatment planned and executed with proper skill, yes it can fail in a month. It is very understandable that you cannot do all your dentistry at once, but there should be an overall game plan, and then execute the plays in the proper order. Perhaps an unstable bite is putting too much pressure on the bonding, and needs to be corrected first? You should have a complete set of X-rays and a complete exam and case presentation by an experienced Cosmetic Dentist. Then decide in what stages you wish to proceed.

Bonding should not be wearing off this quickly if it is done correctly. If you are unhappy with the work done by your dentist, seek out a new dentist that can do a better job for you. Before you commit to treatment, ask to see some before and after pictures of anterior bonding. Make sure you discuss what you and the dentist are responsible for if the bonding does break or stain. If you find the right dentist, they will stand by their work and correct it for you if it fails prematurely.
