Dull or Stained Porcelain Veneers? 5 Tips for Treatment and Prevention

by

If you take good care of them, porcelain veneers can last 15 to 20 years or longer. But what if your veneers look dull or are stained? A skilled cosmetic dentist might be able to help.

Polishing Dull or Stained Porcelain Veneers

Porcelain veneers can be polished to a gloss similar to their original glaze. But your dentist must have the specialized tools, materials, and training to achieve the correct results. Otherwise, your veneers can be permanently damaged.

What’s Involved?

The right tools and materials

Polishing porcelain requires your dentist to use a combination of specific tools and materials that are designed for use on dental restorations.  Some tools and materials might include:

  • Polishing instruments for use on dental ceramics
  • Ultra-fine polishing strips
  • Ultra-fine polishing paste

Maintenance

Porcelain veneers require maintenance to keep their luster. If you schedule regular polishing visits with an experienced cosmetic dentist, it can prolong the life and beauty of your veneers. Any accumulation of stains or dullness on your veneers will be minor if they are properly maintained.

Preventive care

What can you do to keep your porcelain veneers bright?

Avoid abrasive toothpaste – This includes whitening toothpaste that is not designed for use on porcelain veneers. Whitening toothpastes are abrasive and can scratch the surface of porcelain veneers. The tiny scratches will attract stains.

Use a soft bristle toothbrush – Soft bristles will gently clean your porcelain veneers and prevent scratches on the surface.

Use alcohol-free mouthwash – Alcohol can soften and loosen the bonding of your porcelain veneers. Fluid or bacteria can leak behind the veneers and cause staining or decay.

What’s Next?

A family or general dentist who does not regularly place porcelain veneers won’t have the proper tools and materials to enhance the appearance of your veneers. If your porcelain veneers need to be polished, seek the advice of a trained cosmetic dentist. He or she will examine your veneers and let you know the results you can expect.

5 Causes of Sensitivity from Teeth Whitening and 5 Things You Can Do about It

by

Teeth whitening is an easy way to rejuvenate your smile. But what if you experience sensitivity from whitening? Something is wrong. Whitening your teeth should be a comfortable and enjoyable experience. Causes, treatment, and prevention of sensitivity or pain are discussed below.

What Causes Sensitivity with Teeth Whitening?

1. Decay

Untreated cavities get worse and affect the layers of your teeth. When decay begins to affect tooth pulp, which includes nerves, your teeth can become sensitive to heat, cold, and other things—including whitening gel—that come in contact with your teeth.

2. Leaking restorations

If dental fillings or other restorations, including dental crowns, are not correctly sealed or bonded, bacteria and fluids can leak beneath them. The tooth pulp will become irritated. If you use teeth whitening gel while you have a leaking restoration, it can create even more sensitivity.

3. Gingival recession

Receding gums expose tooth roots. The roots can become sensitive to the touch and to temperature changes. Already sensitive roots can be further irritated with teeth whitening gel.

4. Cracks or other damage

If a tooth has a small fracture or other damage, bleaching gel can leak in and create sensitivity.

5. Dentin tubules

Dentin tubules are small channels in the dentin, or middle layer of a tooth, that transfer sensations from outside a tooth to the inside. Although dentin tubules naturally have plugs, the chemical reaction during the whitening process opens the plugs. Some people experience sensitivity to the carbamide peroxide or hydrogen peroxide in teeth whitening gel as it flows to the tooth nerves.

What Can You Do About Sensitivity from Teeth Whitening?

1. Use a lower concentration of whitening gel

There are varying strengths of whitening gel. You might get better results with a less potent gel. It might take a little longer to get your teeth as white as you want, but the experience will be more comfortable.

2. Shorten the whitening session

Reduce the time you wear the bleaching trays. Shorter sessions can limit sensitivity in your teeth.

3. Whiten your teeth less often

Give your teeth a break. Avoid whitening them for an extended period of time, and avoid excessive treatment.

4. Use toothpaste for sensitivity

Some types of toothpaste are designed to reduce sensitivity in teeth. You can use them before and after whitening sessions. Your dentist can provide you with desensitizing gel or paste.

5. Protect your teeth in advance

When you receive teeth whitening from a dentist, a desensitizing agent can be applied to your teeth before and after bleaching sessions. Some dentists ask patients to use desensitizing toothpaste up to two weeks before a whitening session.

What’s Next?

If you are experiencing prolonged sensitivity in your teeth, schedule an appointment with your dentist. He or she will examine your teeth and gums and explain your treatment options.

Dentist-supervised teeth whitening provides safe, comfortable, and predictable results. Speak with your dentist about your options for a brighter smile.
