Entries in root canal (5)

If I Need a Crown...does that mean I need a root canal too?

In a word, no.

This is another one of those common questions I get asked all the time.  When I tell a patient who has a broken down tooth they need a crown to preserve, I am asked about root canal treatment before the crown. People are relieved to hear that a tooth does not need root canal treatment before "crowning" as long as the tooth isTheOakvilleDentist.com healthy.  Generally crowns are to repair broken down or weakend teeth. What gets people confused is that often, after a root canal, a crown is often recommended.  

What's the difference?  

Well root canal treatment results in a weakened tooth, one that can fracture sometimes resulting in tooth loss.  A crown or onlay after root canal will hold the tooth together and allow it to be used for chewing normally. Most of the time a tooth needs root canal treatment because it has either a large cavity or large filling that results in the tooth becoming infected. To treat the nerve in the tooth we end up weakening the tooth further. You may hear stories from people you know who say they had root canal and lost their tooth.  I'll bet 90% of the time it is because they didn't follow their dentists recommendation to crown the tooth afterwards, and it fractures as it it has become structurally weaker.

So now you know the difference.

Infections...can't you just prescribe pennicillin doc?

It is not unusual, even today, to have patients ask for an antibiotic for a tooth ache or dental infection.Pennicillin for a tooth ache?

But I think most people today know that antibiotics are losing some of their effectiveness and usefulness.  Many of my patients have allergies to one or more antibiotics.  And in the news we hear of drug resistant bacteria causing serious infections that we have no drugs to help us fight. What has brought us to this point? Well, it's because antibiotics have been over used.  Here's the thing.  Antibiotics don't cure infections.  Patients cure themselves. Antibiotics give your natural defense mechanisms a chance to catch up.

How long will a (dental) bridge last?

I was at a great lecture last week at the Toronto Academy of Cosmetic Dentistry.  The speaker was one of the gurus we all line up to hear; Dr Carl Misch.  He was talking about dental implants. 

Before we could replace missing teeth with dental implants, the most lifelike way to replace missing teeth was to make a "bridge".  Now you can only have a bridge if there are teeth on either side of the space where the lost teeth were.  These teeth have to anchor the replacement faux teeth and to do that we have to shape them as if they were to be crowned.  Now this isn't without risks - see below.   Dr Steven Rosenblat Oakville Dentst This is not to say you should avoid a crown or bridge but if you have an alternative treatment option that will give you a better result than a bridge, why involve the teeth adjacent to space from missing teeth?

So why do non removable dental bridges fail?

Decay to abcess...as seen in "X-Rays"

I thought I'd post an intersting animation I made a while back.   I occasionally make animations for educational purposes and you may have seen some on this or other websites I have had in the past.  If you are a patient who sees me at my Oakville practice, you have seen this and other dental education I play on the monitors in my office.
Here you can see a cavity start on a tooth that has no decay to start.  Just beside this tooth you can see two teeth with fillings...they look white.decay to abcess -Xray "movie"
As the decay progresses, it gets larger and deeper in a typical manner, eventually reaching the dark area in the center of the tooth.  This dark area in the center of the tooth is the "hollow" inside of the tooth where the "nerve" or dental pulp is.  The pulp is the living part of the tooth.  When the decay reaches the pulp, the bacteria that has caused the decay (destruction of the hard tooth structure) infects the pulp tissue and it dies.  The dead tissue breaks down and abcesses and on this Xray Animation you see a large round shadow form at root tip.  This dark spot is the breakdown or destruction of bone there by the abcessing nerve tissue. 
As you might guess,  I try to get the cavities when they are small and easy to repair.  Once the decay reaches the nerve, root canal therapy is needed and we want to avoid that.  This is one of the reasons we dentists take radiographs or "X-rays" at check ups... to get the cavities when they are small and easy to fix!

Why is it black at the gumline of my crown?

Updated on Saturday, May 1, 2010 at 3:04PM by Registered CommenterDr Steven Rosenblat

Patients often enquire about dark lines that appear at the gumline of crowns.  Sometimes it can be a wide area and there may be darkness appearing around the gums of a tooth that has a crown too.  The reasons are usually related to how and a crown was fabricated and how the light that lets you see your teeth affects your teeth and gums.  A little bit of background information will help explain all of this.

When you look at teeth (or anything you can see) what you are actually seeing is the light that bounces off each tooth.
