A bridge or a removable partial denture?

Tuesday, January 27th, 2009

Dr. Goldstein,
Is a 4-tooth bridge or a partial denture for the upper molars better? Which is less costly? What is the least expensive type of cap or crown available that won’t be seem?
- Judy from Illinois

Judy,
You would need a four-tooth dental bridge if you have two missing teeth, side-by-side. In a situation like this, a bridge would be better than a partial denture, and here is why:

The full name would be a “removable partial denture.” This is where false teeth are fastened to a plate, which is then clasped to your teeth. Not only can this be uncomfortable, but if you don’t take great pains to clean them after every time you eat, it can easily promote decay on the spots where the partial attaches.

But you left out the option that I think is really the best, and that is dental implants. Especially if you have two missing teeth side-by-side, the bridge has a drawback in that it now places all the stress for four teeth onto the two teeth that the bridge is attached to. But if you have dental implants, there is no grinding away of those adjacent teeth, and no extra stress put on them. And the implants will require less maintenance and probably a lower risk of failure or complications down the road.

Cost is another issue. Depending on your dentist, the fee for the dental implants and for the bridge are going to be close to the same, or the implants may be somewhat higher. The removable partial will be much cheaper, at least in the short run. It will probably be around half or even one-quarter of the cost of the other options. Of course, if the teeth that are clasped are eventually damaged and then you lose those or need to have them crowned, the removable partial could be the most expensive option in the long run.

Will Zoom have any effect on tetracycline stains?

I have tetracycline stains on my teeth. Will ZOOM have any effect on it?
- Suzanne in New Jersey

Suzanne,
Tetracycline stains occur because someone took tetracycline antibiotics while the permanent teeth were forming, which would generally be before age 12. What happens is the tetracycline itself actually becomes a part of the dentin of the tooth. It results in a deep, dark brown or gray stain.

These stains are very difficult to remove. Yes, Zoom Whitening will lighten the stains. If you do enough Zoom treatments, it can whiten them quite a bit. They won’t ever be bright, sparkly white, but they will be a definite improvement. Or you can do the regular at home whitening treatments and then just buy enough refills to continue bleaching for several months.

The best treatment for tetracycline stains is to have porcelain veneers to cover over them. But I’d be careful with what dentist you ask to do this. The dentist needs quite a bit of experience with cosmetic dentistry, because it is difficult to cover over the dark stain of the teeth and still have it look lifelike.
