Do I Need to Get a Crown on a Root Canaled Tooth?

Posted on by .

I have a canine tooth that needs a root canal treatment. My dentist also wants me to get a crown. To tell you I’m not fond of dentists is an understatement. I get that I’ll need the root canal treatment. The tooth is infected. That has to be fixed. I get that. Do I have to also get a dental crown? The less time I spend in the dental chair the better.

Dear Kevin,

Man grabbing jaw in pain

You didn’t mention what tooth needed the root canal treatment. A root canal treatment can make a tooth brittle. Some dentists will just try to crown every tooth after a root canal. However, the location of the tooth makes a big difference as to whether or not you’ll need a crown. If it is a back tooth, then I would say the crown is absolutely necessary.

Molars have between two to four cusps, depending on whether they are a premolar or not. When stress is placed on those cusps, like you’d get with biting forces, the cusps pull apart. This causes split fractures. The back teeth are used for grinding so having a crown protects it.

The front teeth, however, are used for biting and tearing. The shearing stress on front teeth means that putting a crown on that tooth will actually put it at more risk of damage. Instead, I would handle it this way. Don’t let him place root canal filling material. This will cause a darkening of the tooth. The better plan is to place a white fiberglass post. Then fill the rest with a white composite filling material. This will protect your tooth and keep it a color you’ll be pleased with.

Dealing with Dental Anxiety

You are not alone in your dislike of the dental chair. I want to suggest you look for a dentist who offers dental sedation. This will allow you to have stress free as well as pain free appointments.

Most patients find this completely changes their lives. It makes it easier for them to get to the dentist. This in turns keeps them from having fewer, if any, dental infections and gives them better overall oral health.

My Dentures Won’t Stay In

Posted on by .

I need some help. I’ve had dentures for over 30 years but I’m having trouble keeping them in. One of the things that my dentist said is the bone ridge is almost completely gone. He said I eventually won’t be able to wear them anymore. Is there anything I can do? How will I eat?

Dear Danni,

I know what is happening as well as the solution. Hopefully, your dentist warned you before you had your dentures placed about the dangers of facial collapse. When your teeth are removed, your body recognizes that. In an effort to be as efficient as possible, it resorbs the minerals in your jawbone to use elsewhere in a manner it perceives more useful. After ten or so years, you begin to lose enough jawbone to notice a problem. By the time you get to thirty years, as you have, you’re in full-blown facial collapse.

The solution is bone grafting. This is a surgical procedure which builds back up the bone in your jawbone. Not all dentists know how to do it, so you may need to do some investigating. Once that is done you have two choices.

Choice Number One: Get New Dentures

Once the bone is better, you can have your dentist make you a new set of dentures. The only issue with that is you will start the same cycle again. Your body will begin the whole cycle of bone resorption again.

Choice Number Two: Get Implant-Supported Dentures

One real solution is to have dental implants placed in order to mimic your tooth roots. This signals to your body that you still have teeth. As a result, it will preserve the jaw bone there as still being necessary.

Generally, you will use four to six implants per arch. After a period of healing, which also allows time for the bone to integrate to the implants, then your dentures can be anchored to them.

Other Benefits of Implant-Supported Dentures

Aside from protecting you from facial collapse, which is a HUGE plus, you will notice right some other great benefits from implant overdentures:

  • Your dentures will no longer move around.
  • Your chewing capacity will increase.
  • You will no longer have to worry about sores from your dentures sliding
