Why Don’t Dentists Warn Patients That Porcelain Veneers Fall Off?

Posted on by .

I got porcelain veneers in February this year. Two of them have fallen off, and one of the two just fell off again last week. So far, none of the others feel loose for now. I am nervous because I’m going to S. America in three weeks. I’m not sure how to find an excellent dentist to bond veneers back on, and I’m not sure it’s a good idea either. My dentist has an accusatory tone about why my veneers have fallen off. He says that it can happen if I’m rough with them. This is news to me. I wasn’t rough with my natural teeth before veneers. I floss and brush as usual.

I’m beginning to wonder what else my dentist didn’t tell me about what to expect with veneers. Is it legal for dentists to withhold vital information like this? My husband thinks my dentist must have done bad work, but this is the same dentist I’ve had for the past seven years. I know other people who have received veneers from him and aren’t having any issues. Interestingly, our dentist did not warn them about the possibility of their veneers falling off. Why wasn’t I warned? Is this common for dentists to keep to themselves? Thanks. Keilah from NH

Keilah – You didn’t receive a warning about porcelain veneers loosening and falling off because it should never happen.

Why Do Porcelain Veneers Fall Off?

Quality porcelain veneers do not fall off

If you have had repeated issues with veneers falling off, it is most likely because of your dentist’s improper bonding techniques. The veneer that fell off a second time wasn’t properly cleaned before it was bonded on again.

Although Dr. Brooksher would need to examine your veneers to determine what is happening, we suggest getting a second opinion before your trip. Find a skilled cosmetic dentist to examine your veneers, check them for stability, and let you know your options to ensure they are secure.

If your veneers are constructed properly, a trained cosmetic dentist can correctly bond them to prevent them from falling off in the future. If any of your veneers are loose, a skilled cosmetic dentist can remove, clean, and bond them on again.

You can decide whether you trust your current dentist to make the corrections, but given his track record, we suggest that you consult with an experienced cosmetic dentist.

Is my electric toothbrush damaging my porcelain veneers?

Posted on by .

Two of my porcelain veneers loosed three times within the past five months. My dentist rebounded them. But during my last visit, my dentist asked me what kind of toothbrush I use. I use an ultrasonic toothbrush and Supersmile toothpaste. My dentist blames my toothbrush on the loose veneers, but I know better. And if a toothbrush could cause loose veneers, I asked my dentist why he didn’t tell me that before I got veneers. Please tell me that I am right, and my toothbrush is not causing loose veneers. Thank you. Max from TX

Max,

Although ultrasonic cleaning devices in a dental office can damage dental bonding or veneers, an ultrasonic or sonic toothbrush will not harm them. Let us explain the difference.

Is Your Toothbrush Damaging Your Porcelain Veneers?

Your toothbrush is not damaging your porcelain veneers. And there is a difference between ultrasonic dental tools and your toothbrush.

Ultrasonic dental tools

Ultrasonic dental tools have metal tips that can damage bonding or veneers. The devices can crack the glaze on porcelain veneers. And professional ultrasonic speeds are much higher than your toothbrush.

Ultrasonic toothbrush

An ultrasonic toothbrush has soft bristles that will neither nick bonding or veneers. Instead, they polish your veneers and clean them. And toothbrushes are usually sonic—not ultrasonic—which means their vibration speed is slower and more gentle than dental equipment.

What Is Causing Loose Porcelain Veneers?

Porcelain veneers do not loosen if a dentist bonds them properly

Loose porcelain veneers result from failure of your dentist’s bonding technique, aggressive preparation of your natural teeth, or both.

  • Aggressive tooth preparation – Often, a dentist who lacks advanced cosmetic dentistry training removes too much tooth enamel when preparing teeth for porcelain veneers. As a dentist removes more enamel, it becomes difficult for the bonding to adhere to your teeth. And if a dentist grinds your teeth down to the dentin (the layer beneath the enamel), it increases the risk of veneers falling off.
  • Bonding technique – Dentists who take advanced cosmetic dentistry training after dental school learn techniques to bond porcelain veneers securely to your teeth. And they know the importance of removing excess bonding material to avoid irritation and inflammation.

Get a Cosmetic Dentist’s Opinion

Although your dentist is blaming your toothbrush for loose porcelain veneers, that is not the problem. We recommend that you schedule a consultation with a skilled cosmetic dentist to examine your teeth and veneers to identify the issue. A cosmetic dentist will explain the treatment options to keep your veneers intact.

Can I Get Only One Porcelain Veneer Replaced?

Posted on by .

I received six porcelain veneers in May 2019. My dentist didn’t get the bonding quite right on one veneer, and I had a lot of sensitivity in the tooth. At first, he suggested that I use Sensodyne toothpaste, but it didn’t help much. I mentioned the sensitivity at my next dental cleaning appointment, so my dentist looked at the tooth and said that the veneer is not in its original position and the dentin is exposed. He suggested replacing the veneer (upper left center) and the right-center veneer next to it to ensure the veneers match. I’m disappointed because this dentin exposure business was my dentist’s fault. Why did the porcelain veneer move out of place? He offered to reduce the cost of replacing the two veneers, but I don’t think I should have a fee at all. And why can’t he just replace the one veneer anyway? I’m afraid that if he must remove the veneer on my right front tooth that it might become sensitive, too. Should I insist that he only replace one veneer? Thank you – Zachary from GA

 

Zachary,

You didn’t mention if your general or family dentist provided the veneers. But it seems that you saw a dentist with limited training in cosmetic dentistry who aggressively prepared your teeth.

Is It Possible to Replace One Porcelain Veneer?

A skilled cosmetic dentist can replace a single porcelain veneer

Yes, it is possible to replace a single porcelain veneer. Any dentist with advanced cosmetic dentistry training can replace one veneer and perfectly match the color with your existing veneers. Dentists who are skilled in aesthetics use dental laboratories that keep color formulas for each patient’s case so they can perfectly match it in the future.

Dentin Exposed with Porcelain Veneers

When a dentist prepares your teeth for porcelain veneers, and the dentin is exposed, they over-prepared your teeth. When tooth preparation is necessary, skilled cosmetic dentists only remove a fraction of a millimeter of tooth enamel for several reasons:

  • Preserve as much tooth structure as possible
  • Provide better bonding—veneers adhere better to tooth enamel than dentin, which is softer.
  • Avoid exposing dentin because dentin tubules lead to the pulp and risk irritation and infection.

Insist on Replacing One Veneer?

If your dentist says he must replace veneers on both central incisors (center front teeth) to achieve a color match, he probably doesn’t know how to do otherwise. You can decide if you trust your dentist to do the work or want a second opinion. If you choose to get a second opinion on your porcelain veneers, look for a dentist with post-graduate training and experience in dental aesthetics.

You probably want to get the issue resolved quickly, so don’t delay—especially because dentin exposure is unhealthy for your teeth.
