Sleep Apnea and Dentistry

Did you know that if you have sleep apnea that it can shorten your lifespan by 7 to 8 years? Did you know that having sleep apnea puts you at greater risk for stroke or heart attack?

Obstructive sleep apnea is defined as someone that stops breathing while sleeping. Sometimes this can be accompanied by loud snoring. The cessation of breathing is caused by muscles in the throat area relaxing and the tongue falling back in the throat, blocking the airway. The severity of sleep apnea is defined by the number of times per hour someone stops breathing in their sleep. Someone with severe sleep apnea stops breathing more than 25 times per hour while they are sleeping. The body subconsciously wakes up when it realizes it isn't breathing, leaving the person to wake up the next morning feeling unrefreshed.

My dad has sleep apnea. In his quest to treat his own condition he took a continuing education class on treating sleep apnea with dental appliances. After taking the class, he decided to invest in an airway evaluation device as well some take home sleep monitors. In the past couple of months he has successfully treated a number of mild to moderate sleep apnea patients with dental appliances. (If someone is found to have severe sleep apnea, then a continuous positive airway pressure machine is recommended.)

As a part of our sleep apnea screening we ask the following questions:

1. Are you likely to fall asleep or doze off if you are:
a. Sitting and reading
b. Sitting in a public place
c. Driving a car stopped for a few minutes in traffic
d. Sitting down quietly after lunch without alcohol
e. Watching TV
f. As a passenger in a car for one hour
g. Sitting and talking to someone
h. Lying down to rest in the afternoon
2. Have you gained 15 pounds or more in the last six months?
3. Have you ever been told that you snore?
4. Does your snoring occur almost every night?
5. Would you or someone hearing you sleep consider your snoring louder than a person talking?

If you answer yes to two or more of the above questions, then you could be at risk for sleep apnea and an evaluation of your airway opening would be a good idea.

Cavity prevention with mouthwash

I pulled this pH scale image from the CariFree website. What is CariFree? CariFree is an entire product line of mouthwashes, toothpastes, gum, and mouth sprays that were developed to have basic pH content, xylitol, and fluoride. The most impressive part of their product line is the mouthwashes. They have a CariFree treatment rinse and a CariFree maintenance rinse. What sets apart the CariFree rinses from others on the market is that they are basic in their pH. The CariFree system of products is a relatively new product line and something that I have only had in my office since May of this year.

I have a patient that has recently been struggling with dry mouth and tooth decay. We set up an appointment so we could further discuss treatment options for prevention of future tooth decay. My patient took it upon himself to bring in some pH strips and the Biotene and ACT brands of mouthwashes to his appointment. I was surprised to find out that the Biotene rinse was a 4.5 pH which is quite acidic. The ACT brand was neutral at 7.0 pH.

It is scary that a rinse like Biotene which is marketed to dentists as a treatment for dry mouth, could actually be causing more harm due to its acidic content. It would be like rinsing your mouth with 7-UP soda. There are many other mouthwashes out there that contain alchohol which apparently is meant to kill bacteria, but it leaves the mouth dry which ultimately encourages bacterial growth.

Since we started distributing the CariFree rinse in May, I have had a number of patients use the rinses. The most common testimonial I hear is that it helps with dry mouth and it makes the teeth feel cleaner.

My recommendation to my patients is that if you are going to use an over the counter rinse, the ACT rinse is your best bet. It has fluoride and it is at least neutral in its pH. If you want a rinse that will help neutralize the mouth and stop de-mineralizing your teeth, then I recommend taking a look at the CariFree product line.

Another Cavity?

There are three groups of people that tend to get new cavities on a routine basis. The first group are children under 10, the second group is teenagers, and the last group is mature adults (the 60 and over crowd). My least favorite thing to do in my office is to inform someone that they have another cavity.

On a routine basis now I am asking a couple of key questions as part of my patient health history review. The purpose of the questions is to initiate a dialog as to what causes tooth decay and how to prevent it from happening in the first place.

The risk assessment for cavities includes the following: Acidic beverages, frequent snacking, inadequate salivary flow, appliances present, deep pits and fissures, hyposalivary medications, visible plaque, cavity in the last three years, visible cavitations and radiographic lesions.

Basically in order to get a cavity, something acidic sits next to the tooth structure and eats away at the tooth structure to form a hole in the tooth. What we eat and drink and how often we eat and drink it plays a large role in how much acidity is in our mouth. Anything other than water such as: soda, juice, energy drinks, vitamin waters, and carbonated beverages are acidic. Anything dry, pasty or sugary contributes to the food particles staying in the mouth for a longer period of time. The solution when it comes to tooth decay, is to limit food consumption to meal time and only drink water outside of meal times.

Braces, inadequate salivary flow, deep pits and grooves on the teeth, and lots of plaque on the teeth are all things that contribute to the acidity having an easier time to stay next to the teeth for a longer period of time. I recommend an electric tooth brush for all of my patients, as well as a daily flossing routine in order to maximize the cleanliness of the teeth.

A cavity in the last three years, visible cavitations, and radiographic lesions are important because it means that the cavities are significant enough that they must be removed and filled by the dentist. Even though a tooth has had a filling or a crown, it can still get new tooth decay in the future. Basically any part of exposed tooth structure is susceptible to tooth decay.

Wonder why the three age groups I mentioned at the beginning tend to get the most new cavities? The under age 10 group is at risk because of drinking milk right before bedtime or other non-water beverages throughout the day, eating sugary snacks and candies like gummies or fruit rolls, and not being able to effectively brush or floss their own teeth. The teenager crowd is at risk because of braces, consuming large amounts of alcohol and not brushing before bedtime, and snacking or drinking awakening beverages while studying. The mature adult is at risk because of the medications that they take that changes their body chemistry and dries out the mouth.
