Is My Tooth Cracked Beneath a Dental Bridge?

Posted on by .

After my routine hygiene and dental exam last week, my dentist said I needed a new upper left bridge. She said an anchor tooth in the bridge was cracked. I don’t have problems with the bridge, nor have I felt any discomfort. Should I deny a new bridge if I don’t have symptoms? Thank you. Portia

 

Portia,

Your dentist’s diagnosis should accompany an X-ray showing your tooth is cracked. Generally, you would feel sharp pain when biting hard food if a tooth is cracked. Also, it is unusual for a crowned tooth to crack. A crown protects a weak tooth and prevents it from cracking.

We recommend getting a second opinion from an advanced cosmetic dentist without mentioning your dentist’s diagnosis. Ask for an exam and X-ray, but provide as little information as possible. Avoid telling the dentist that you or your dentist think your tooth beneath the bridge is cracked. You might ask if the dentist seeks anything questionable about your upper left teeth.

Dental implants can anchor a bridge and replace multiple missing teeth in a row

Your situation underscores the advantage of replacing a tooth with a dental implant. If anything goes wrong with a tooth that is a part of a dental bridge, a dentist usually replaces the entire bridge. However, a dental implant stands alone and is not affected if you need dental work on an adjacent tooth.

If your tooth beneath the bridge cracks, a dentist must remove the tooth and extend the bridge to cover the space left after the extraction. Consider getting a dental implant or an implant bridge as an alternative to traditional bridgework to replace missing teeth.

What Happens If I Don’t Replace Missing Teeth?

Posted on by .

I have opted for my dentist to pull teeth for the last ten years instead of doing root canals and caps. Now I am missing four upper back teeth. All my wisdom teeth are gone, so the two teeth in front of them on both sides of my upper jaw are missing. You cannot tell the teeth are missing unless I hold my head back and laugh. Now that I moved to Massachusetts, I have a new dentist suggesting that I replace my teeth with dental implants. She says I will regret it as I get older if I do not get the implants when my teeth start shifting around. She can already tell from my x-rays that my teeth are moving, and she showed me the x-ray comparison. I’ve had this dentist for three years, and I trust her. But a second opinion is always good. I am not considering dental implants yet. Why not get a dental bridge? What will happen if I don’t replace my missing teeth? Thank you. William from Springfield, MA

William,

Thank you for your question. Your dentist may be persistent, but she seems to be genuinely concerned about your long-term oral health if you do not replace your missing second and third molars.

What Happens If You Don’t Replace Missing Teeth?

If you do not replace missing teeth, it can affect your long-term oral health in these ways:

  • Tooth misalignment – Teeth are placeholders for proper alignment. Gaps in your smile cause teeth to lean against each other and crowd your smile. When teeth are missing, other teeth will begin to drift toward the spaces.
  • Jawbone shrinkage – In areas of missing teeth, the jawbone shrinks 25 percent within the first three months and up to 50 percent within six months. Multiple missing teeth can accelerate facial wrinkles and sagging.
  • Challenge with oral hygiene – It is challenging to brush and floss between teeth that lean on each other. Crowded teeth increase the risk of plaque and tartar buildup, tooth decay, and gum disease.

Why Get Dental Implants?

A complete dental implants replace a tooth’s roots and crown

A complete dental implant replaces a tooth’s root and crown. The artificial tooth roots fuse with your jawbone and look and feel natural. A dental bridge requires shaving down the tooth on either side of the missing one. But you are missing second and third molar teeth with no teeth behind them to support a bridge. Although a dentist may offer alternative bridge treatment, other teeth will need to support it. The option will be less healthy than individual implants.

We suggest that you discuss your concerns with your dentist and ask for more information on dental implants and what you can expect with or without them in the long term.
