I’ve had porcelain veneers for 20 years and they have lasted just about the length of time my dentist said they would. I got them because my teeth were stained by tetracycline and at the time, whitening treatments were not readily available like they are today. I would have liked to have gone that route, but my dentist said whitening treatments aren’t really effective on tetracycline stains.
I’ve been pretty happy with my teeth, however, in the last six months to a year, I have noticed a gap forming between the veneers. When I eat, food seems to get caught. Also, I am starting to have a space at the top of the veneers and the gum line. Can my veneers be removed for new ones or is there a way that I can “refurbish” them? — Nancy
Nancy,
Your dentist was correct in the fact that teeth whitening or bleaching is not a good option for tetracycline staining. Even if you had been able to lighten your teeth, they would never have been perfectly white.
It is possible to touch up porcelain veneers by polishing them and smoothing off the margins. However, what you are describing sounds like you might need to have them replaced. The space developing between the veneer and your gumline is likely a result of your gums receding a little and exposing some of the tooth. With tetracycline staining such as yours, it could be noticeable if the space continues to get worse.
If you have to go the replacement route, be sure to do your homework. Many dentists who say they can cover tetracycline stains often lack the skill and artistry required for true, high quality cosmetic dentistry – and these stubborn stains require the best cosmetic dentist you can find.
As for the life expectancy of veneers – even though your dentist told you they would last twenty years they could have possibly lasted longer. Your situation sounds more like the issues may have been caused from changes specific to your teeth, rather than the veneers deteriorating themselves.
