How Long Should a Denture Last?

I was recently asked "how long should a denture last"? Good question.

The short answer is approximately 5 years. The more detailed answer is a little more complicated.

First, let me explain what happens when people lose teeth and choose dentures as the restorative option rather than implants.

When teeth are lost, the bone that surrounds each tooth is eventually lost as well. This process is called resorption. When the bone is no longer under the forces of chewing, it pretty much disappears. This is not much different from when a person loses the ability to use one or more of their limbs for whatever reason. For example, if people are confined to a wheelchair or cannot use an arm that has broken, then the muscles and the bone will atrophy. 

There is a rapid amount of bone loss that occurs within the first six months after the loss of a tooth. It pretty much slows down after this healing period. However, bone will continue to be lost throughout life. A small amount of bone loss may not appear to be a big deal. If for example someone loses approximately 0.5 mm of bone each year, then we may not perceive it to be an issue. If however, we get 0.5 mm of bone loss for 10 years, that's 5 mm. NOW it's a big deal.

So, how does all this relate to how long a denture will last? 

The girls I employ mock me (with love of course) by telling me I am the Analogy King. I will therefore have to provide yet another analogy. 

Let's say you buy a pair of shoes today. The shoes will certainly fit at this time. But what if your feet shrink significantly for the next six months? At this point you would have to either purchase a new pair of shoes or wear more socks. 

So, with a denture, you would either have a temporary denture for the first six months and get a replacement, or just reline the original denture. 

So how long does it last?

Well, it depends on how fast bone is lost.

So, you see that there truly is no simple answer. If you have a loose fitting denture, it's time to reline or replace it. The problem with an ill-fitting denture is that it will cause the bone to resorb even faster.

If you have any doubts, have your dentist evaluate the fit.

Top 5 Myths About Snoring

Not too long ago (and even today), most people believed that snoring was normal and completely harmless. We thought it was just a minor nuisance to the people that had to hear the snoring. We thought that it was a sign of restful sleep. We thought that it wasn't really that big of a deal.

There are quite a few myths in regards to snoring. Here is my top five list of the ones I hear most often:
  1. Snoring is normal
  2. Only overweight people snore
  3. You don't have sleep apnea if you don't snore
  4. You are certain you don't snore
  5. Children don't snore
Let's address each of these myths.

1. Snoring is Normal

Snoring is very common. However, it certainly isn't normal. 

When we are breathing properly, air flows smoothly through the respiratory tract and there is virtually no sound. Perhaps just the sound of air flowing. 

When we snore, there is an obstruction that impedes proper airflow. Most often, the obstruction is caused by the tongue or the soft tissue in the back of your throat.

We all know that proper ventilation is vital to life. When we aren't getting an adequate amount of air, neither is your heart, brain or other vital organs. 

2. Only Overweight People Snore

Yes, it is true that overweight people snore because of their enlarged necks which will often constrict the diameter of the airway and therefore decrease airflow.

I often see very thin people in my office suffering from Obstructive Sleep Apnea caused by some restriction of airflow just as you see in overweight people.

The causes can be anything from chronic sinus issues, to jaws that are excessively skinny that can't accommodate the soft tissue tongue and tonsils. These structures pretty much get in the way.

3. You don't have sleep apnea if you don't snore

Nope, not necessarily.

People that stop breathing because of a complete blockage of the airway do not snore because there is no flow of air to cause snoring. You'll often see these people actually stop breathing for extended periods of time until they briefly awaken to catch their breath. This process can repeat for the entire night.

4. You are certain you don't snore

The only way to determine if someone is or isn't suffering from sleep apnea is to have a sleep study performed. 

We now have the option to perform a sleep study in your own bed without people there to watch you sleep. It used to be a major obstacle to get people to go to a sleep center. That is no longer the case.

5. Children don't snore

Not true. Children can have the same issues as adults. In fact, when they have enlarged tonsils, they often inhibit proper airflow.

Some warning flags may include ADHD, bedwetting, profuse sweating during sleep and kicking during sleep.

A Call to Action

The real problem isn't snoring. The real problem is Obstructive Sleep Apnea. We can determine the severity by doing a simple sleep study. This is the only way to objectively evaluate the severity. 

Many of my patients may require no treatment whatsoever. However, many do. The problem with Obstructive Sleep Apnea is that it kills people. On average, you can expect a 12-15 year loss of life.

Some warning flags include narrow faces, enlarged necks, obesity, daytime sleepiness, chronic fatigue, hypertension and mouth breathing to name just a few.

If you snore or suspect that you (or a loved one) may be suffering from Obstructive Sleep Apnea, I urge you to get evaluated. It could save your life or the life of a loved one.
