On top of that, daily habits like drinking coffee, as well as genetics and certain medications, can lead to significant discoloration. Therefore, some people choose to get porcelain veneers in Mankato. Not only do veneers cover up dark or dull teeth, but they can also provide years of stunning, stain-free smiles. Here is a look at the science behind why porcelain veneers do not lose their luster like natural teeth do.

Porcelain is Non-Porous

High-quality veneers are made out of dental porcelain, which is a non-porous substance. That means that things like coffee and red wine simply slip off of the veneers; the pigments do not soak into the porcelain and cause it to become discolored.

The non-porous nature of veneers is in stark contrast to that of tooth enamel, which is covered in microscopic openings, or pores. The main function of the pores is to allow substances to interact with the teeth’s interior layers so you can tell if a food hard or soft, hot or cold. Unfortunately, the pores also allow pigments from what you eat and drink to infiltrate the teeth and lead to stains.

So Veneers Never Stain?

Veneers can retain their brilliant luster for many years. However, they can start to look a little dull or discolored over time. This may happen if you accidentally create little scratches in the porcelain where pigments from food and drink can get stuck.

Maintain Your Veneers’ Beauty

Here are some tips you can use to help your porcelain veneers maintain their beauty:

  • Be choosy about your toothpaste. Many toothpastes are slightly abrasive in nature, which can lead to tiny scratches in your veneers. Ask your dentist or hygienist for recommendations on which toothpaste you should use.
  • Visit your dentist for professional cleanings and checkups. Your hygienist or dentist will polish your veneers during these appointments to keep them looking as bright and brilliant as possible.
  • Avoid smoking. Although tobacco will not stain the porcelain, it can discolor the bonding material that attaches the porcelain to your teeth.
  • Protect your veneers from breakage. Just like natural teeth, veneers are vulnerable to breakage if they are misused or become the victim of an accident. Therefore, you should not use your teeth as a tool or to chew on ice or other hard objects. You should also always wear a mouthguard when you play sports.

Are you tired of putting up with a dull, discolored smile? Ask your cosmetic dentist in Mankato if porcelain veneers are right for you.
