Can I lose calcium from my teeth?

Being a dentist, I get to meet all sorts of interesting people.  We chat about all sorts of things.  It's especially fun for me when a patient is in a technology field because as all my patients know I'm into computers and photography.  And when a patient like Terry comes in my assistant Pam gets out of the way because she knows we'll be talking about cameras for 20 minutes.aging smile,

Terry said something interesting the last time he was in.  He was concerned about losing the calcium in his teeth as he ages and how that will result in the breakdown of his teeth.  It's a common thing I hear from many of my patients in their retirement years.  But it is a misconception.  People think teeth and bone are basically the same in how they get and store calcium.  But teeth and bone are two very different things.

Bone is a very dynamic "material".  It is alive and constantly reforming.  In bone itself there are cells that produce new bone and cells that tear down old bone.  Calcium can be added and lost. That is why a fractured leg can heal, new bone is produced to connect the broken parts.  But teeth are pretty static.  More like a crystal.  The living part of a tooth is in the centre only ( ie the "nerve") and the only new tooth structure that is produced thoughout a person's life is inside the tooth. When  the nerve is trying to protect itself from some irritant ( ie decay) it tries making more tooth (dentine) to keep away from the irritant- like the layering of the rings of a tree you see when it's cut. But this is very limited and no dentine is removed by the living nerve of the tooth.  So a broken tooth can't heal like as a broken bone can.

The damage to teeth as people age is due to wear and tear and changes in a persons health.  For example older people often have increasing amounts of decay because their protective saliva flow decreases due to age and medictions ( ie blood pressure medication) . Combine this and the recession of the gums that exposes the more cavity prone roots of the teeth.  The roots of the teeth are always more susceptable to decay ( no enamel) and with less saliva to wash away food the teeth can decay more easily.  Elderly people also have a harder time holding and using a tooth brush (ie arthritis...)so their brushing is less able to keep up with their increased suceptability to decay.  And of course, through the passing of time fillings have been replaced and gotten larger and therefore weaker and more easily fractured.

So as you can see, the refrain I often hear from elderly patients about their teeth losing calcium and falling apart is really an aging process.  To help our seniors keep their teeth and ability to eat comfortably they need increasing help: seeing a dentist and his or her team. And seniors are great patients, I love treating them!

Dental Implants & Crowns can improve a smile...

I've written before about dark gumlines and tooth roots and I see quite a few patients with this problem.  It has also been a popular topic here on this site too so I thought I would post another case.four new all ceramic crowns and one dental implantold failed crowns

Cindy ( not her real name of course) wanted to improve her smile by replacing four crowns on her upper front teeth.  You can see the two on your left have darkness showing through her gums.  The tooth indicated by the red arrow had to be removed.  I replaced this tooth with a dental implant and porcelain crown.  This helped esthetically as the roots of the two center teeth on the left were black from old failed dentistry and replacing one with an implant helped remove some of the darkness, allowing for pinker gums.  Due to the blackness of the root under the gums I couldn't make  much improvement in the tooth on the far left.  See the after image.  With a small bit of trimming we could have perfected the length of her left implant tooth but Cindy was happy with the teeth as you see them and the smile she now has.

( If you want to see what the teeth looked like after I removed the old crowns, just click on the left image.)


Decay to 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!


What do I do if my child knocks out a tooth?

Kids can find many ways to knock out teeth. Swimming pool accidents seem to be the biggest cause this time of year. Running on slippery, slick cement and ceramic pool surfaces sends many children headfirst into the ground, often causing chipped or displaced teeth.
