Why Are My Porcelain Veneers Turning Dark in Just 3 Months?

Posted on by .

Four of the eight porcelain veneers I got in August are turning dark. I’ve been back to the dentist three times, and all she does is look at my teeth and say that she isn’t sure what is going on. My veneers will soon look worse than the teeth beneath them. Since my dentist hasn’t done anything to determine what’s going on, I want a second opinion. It would help if you could give me a few ideas of why the veneers are turning dark so I know whether to trust a new dentist. Thank you. Monet from Charlotte, NC

Monet,

Thank you for your question. Dr. Brooksher would need to examine your teeth and veneers to identify the problem. We will discuss three factors that can darken porcelain veneers.

What Causes Porcelain Veneers to Darken?

Porcelain veneers can darken from power-polishing dental equipment, excess composite, or bacteria leaking between your teeth and the veneers.

  1. Bacteria between your teeth and veneers – If a dentist bonds your veneers but leaves small gaps between the veneers and your teeth, bacteria can leak in and attract stains. Prolonged bacteria lead to tooth decay, which can further darken teeth.
  2. Excess composite during bonding – Excess composite left around the veneers can cause them to darken. A cosmetic dentist can polish away the extra composite to lighten your porcelain veneers.
  3. Dental power-polishing equipment – Power-polishing equipment in the dental office can damage the glaze on the veneers, attract stains, and darken them. Dentists and hygienists trained in caring for veneers understand which instruments to use and avoid while caring for your porcelain veneers.

Can a Dentist Polish Your Veneers?

A trained cosmetic dentist can use ultra-fine polishing strips and aluminum oxide polishing paste on porcelain veneers for these benefits:

  • Help them resist stain
  • Prevent plaque accumulation
  • Smooth the area around veneers
  • Prolong the life of your veneers

Skilled cosmetic dentists have the tools, materials, and techniques required to polish your porcelain veneers and restore or replace them. After an exam, the dentist will explain the condition of your veneers and how to correct them. Look for dentists with advanced cosmetic dentist training for a second opinion.

Why do my veneers make my teeth look thick and bulky?

Posted on by .

One of my best friends and I both received porcelain veneers about six to eight months apart. But my veneers make my teeth look thick and bulky. We went to the same dentist, and he used the same veneers on both of us. My friend got veneers to make her teeth look larger, but I wanted veneers because my teeth were inconsistently shaped and uneven at the edges. My friend’s smile looks beautiful, which is why I used her dentist. She received no-prep veneers, so I asked for the same type.

I’m disappointed with the results from my smile (eight upper veneers) because my teeth look thick and bulky. The dentist explained that sometimes that happens with no-prep veneers. But if the dentist knew the results, why wouldn’t he tell me how they would look? And yes, I did try on temporary veneers, but I let the dentist convince me that I would get used to my “fuller” smile. Why did I get such drastically different results? Will I have to start over with veneers? Thank you.  Kennedy from Memphis, TN

Kennedy,

From your description, it seems that your friend’s case was successful because her teeth were small, and she wanted to enlarge them. The results of no-prep veneers vary with each patient. And not every patient is a candidate for no-prep veneers.

Thick and Bulky Porcelain Veneers

Your porcelain veneers can make your teeth look thick and bulky if you have average-sized or large teeth and your dentist doesn’t prepare them first. Even ultrathin veneers—as thin as 0.3 mm—add thickness to your teeth and slightly extend their length. Cosmetic dentists with advanced training in aesthetics use several brands of veneers and select one to match your case and your smile goals. And they work with master ceramists to ensure give you beautiful results.

Although Dr. Brooksher would need to examine your teeth, minimal preparation is probably the solution to helping your veneers fit well and look natural.

Correcting Thick or Bulky Veneers

If you want to correct the look of thick or bulky porcelain veneers, we recommend that you schedule a consultation with an advanced cosmetic dentist. You can ask your dentist to redo your veneers, but based on your experience, you will probably be disappointed with the results again.

  • Look for a dentist with accreditation from the American Academy of Cosmetic Dentistry (AACD) or the American Academy of Esthetic Dentistry (AAED).
  • Read the dentist’s patient reviews about porcelain veneers and the results.
  • Ask to see the before-and-after photos of the dentist’s patients who had cases like yours.

A cosmetic dentist will explain your treatment options. And unlike your current dentist, they won’t try to convince you that you will eventually like your smile. Skilled cosmetic dentists don’t bond veneers to your teeth unless you are confident that your smile is exactly as you want it.

Best wishes for a beautiful smile.
