Is Whitening the Right Way to Remove Brown Teeth Stains?

Posted on by .

Over the past two years, I began to get brown stains on my teeth that are increasing. I see my dentist twice yearly, and she notices the stains, too. My dentist recommends whitening my teeth, but neither of us knows what is causing the stains. My dentist says the source is probably not serious because I am in my 50s, and the stains are just developing. I asked my primary care doctor about the stains, and he told me to check with my dentist first. I feel like I am stuck in a loop. Yesterday, a friend mentioned that I could research dental bonding if whitening does not work. Should I let my dentist whiten my teeth or get a second opinion? Thank you. Omari from CT

Omari,

Thank you for your question.

We are unsure why your dentist has not tried to identify the cause of the stains and recommend treatment. But you can ask her what might be causing the stains to understand why she recommends whitening your teeth.

Types of Tooth Stains that Develop in Adults

When stains develop during adulthood, they are either internal or external stains.

  • Internal stains – Internal stains can form as your teeth absorb pigments from foods and drinks, such as tea or coffee. Internal stains are even in appearance and affect the entire teeth, and bleaching can break them down. Some prescription medications can cause external stains, too.
  • External stains – External stains appear around your gumline and between your teeth. Some toothpaste brands, such as Supersmile, remove the sticky film (protein pellicle) from your teeth and stains that stick to it. Also, Supersmile toothpaste works because it removes the protein pellicle on your teeth and the stains that adhere to it. Your dental hygienist can remove surface stains.

Identifying the Cause of Tooth Stains

Sometimes a health condition or medication can cause discoloration in teeth. Ask your dentist to review your medical and prescription histories. If neither health nor medication is a factor, your dentist’s recommendation makes sense.

Will You Need Teeth Bleaching or Dental Bonding?

A cosmetic dentist can identify the cause of, and treat, brown teeth stains

Whether a dentist uses teeth bleaching or dental bonding depends on the cause of the tooth stains. If your teeth stains come from coffee or tea, whitening from your dentist will break them down. Dental bonding is usually not necessary unless internal tooth stains develop from medication, fluorosis, or a medical condition.

Teeth whitening from a dentist is safe and can help your smile look younger. If your dentist is not willing to identify the cause of the stains, you can look for a dentist with cosmetic dentistry training to help you.

Does Shaving Down Teeth for Porcelain Veneers Cause Sensitivity?

Posted on by .

Some people who experience sensitivity in their teeth wonder if the sensitivity will increase after a dentist shaves down their teeth in preparation for porcelain veneers.

Porcelain Veneers and Tooth Shaving – The Real Concern

A porcelain veneer only covers the front of a tooth

If a dentist has mentioned shaving down your teeth for porcelain veneers—run. Your teeth don’t need to be shaved down to receive porcelain veneers. A veneer only covers the front of a tooth. However, if you are receiving porcelain crowns, your teeth will need to be tapered because a crown completely covers a tooth.

Preparing Teeth for Porcelain Veneers

Most advanced cosmetic dentists will preserve as much tooth structure as possible when you receive porcelain veneers. Your dentist will determine if preparation is needed depending on several factors, including:

  • the type of veneers you are receiving
  • the position of your teeth
  • your smile goals
  • your dentist’s technique

No-prep veneers

If you’re receiving ultra-thin porcelain veneers, your cosmetic dentist might determine that your case does not require preparation of your natural teeth. One example is that if you want your teeth to look larger, thicker, or more pronounced, preparation might not be required.

Minimal-prep veneers

Skilled cosmetic dentists conservatively prepare teeth for porcelain veneers while leaving at least 90% of tooth enamel intact. There are several advantages to ultra-conservative preparation.

  • Comfort – It only removes a small fraction of tooth enamel, which is non-sensitive tooth structure.
  • Bonding – It does not affect the dentin—the layer beneath the enamel. When tooth preparation reaches the dentin, it’s tricky to get the porcelain veneer to stay bonded. And sensitivity can result.
  • Health and appearance – Bonding to enamel instead of dentin provides a seal that keeps bacteria out and prevents microleakage. When bacteria can leak in and affect the dentin, it will cause the veneers to look dark, and infection can occur.

Look for an advanced—preferably accredited—cosmetic dentist to place your veneers. Your dentist will ensure that if preparation is needed, it will be minimal.

Will You Experience Sensitivity?

If your teeth are healthy and you receive no-prep or conservatively prepared veneers, you probably won’t feel any sensitivity after your veneers are placed. Patients who receive more aggressive preparation might temporarily experience mild sensitivity to heat or cold that lasts a few days up to a few weeks.

The dentist you select impacts the extent of preparation of your teeth, sensitivity issues, as well as aesthetics. We recommend that you find a dentist with advanced training in aesthetic dentistry. Look for a nearby accredited cosmetic dentist.

Is it true that I can’t use toothpaste on porcelain veneers?

Posted on by .

I was told that if I get porcelain veneers that I can’t use regular toothpaste on them. Do porcelain veneers require special care beyond natural teeth? Thanks. Bridget

Bridget – You should treat porcelain veneers as you would your natural teeth. Floss and brush them, but use a non-abrasive fluoride toothpaste.

It’s important that you get your teeth regularly examined and cleaned by a cosmetic dentist with staff training in maintaining porcelain veneers. Some of the equipment used to clean and polish natural teeth will damage porcelain veneers, so it’s important to have a dentist who is skilled in caring for veneers.

Cracked 2 teeth playing musical chairs. Which cosmetic dentistry is best?

Posted on by .

Over the weekend I was bar hopping with some friends. We ended up drinking more than I thought we would, singing karaoke and playing musical chairs until late. I didn’t make it in a seat and my feet slipped out from under me. When I fell I also slid and my teeth hit the metal on one of the chairs. I now have a crack to in two different teeth. Won’t be repeating that performance. What cosmetic treatment will work best for me a veneer or a crown? – Tim

Tim – Your teeth need to be examined by an experienced cosmetic dentist. The treatment that will be recommended will depend on the length and severity of the crack in each tooth.

It is possible that your teeth can be restored with dental bonding. After your teeth are roughened, composite bonding that matches the color of your teeth will be applied to them. The bonding will be smoothed, shaped, and polished for a natural look. You will have to be careful to avoid an excess of food and drink that can stain your bonding, such as berries, coffee, tea, and colas. Tobacco use can also stain bonding.

Porcelain veneers and porcelain crowns are more stain resistant. They are also more durable than dental bonding, which will wear and need to be replaced in a few years.

If you are fortunate enough to find an accredited cosmetic dentist, the results with the restoration of your teeth will be so beautiful that you won’t be able to tell the teeth were once damaged.

Rough edge on porcelain veneer

Posted on by .

On the right side of my mouth, the third tooth from the front, there is a rough edge on the porcelain veneer. I noticed it about 3 weeks ago. I have had the veneers for 4 years. Is this normal? Thanks. Jan.

Jan – No, it’s not normal to have a rough edge on a porcelain veneer. But it can occur.

If veneers are polished at a dental office with abrasive instruments, or if acid fluoride treatments are used, the glaze on the veneers can break. The veneer will become porous and rough.

Biting hard objects, such as pins, nails, or bottles can cause the veneers to fracture.

Visit an expert cosmetic dentist to have your veneers examined. He or she will determine if your veneers can be polished, or if another treatment is appropriate.
