Impact of Dry Mouth on Dental Caries

Dental caries is demineralisation of the tooth surface caused by acids that are produced by bacteria in the mouth. Cavities are formed due to a prolonged loss of minerals such as calcium and phosphate. This loss happens from enamel and dentine. Such acids are washed away by saliva, which is the body’s natural defence against tooth decay. Saliva helps in neutralising acids in the mouth and puts minerals back into your teeth. 

A lack of saliva results in a dry mouth. Eventually, this leads to tooth decay and wear out. Moreover, gum problems also become prevalent without adequate flow of saliva. The most common causes of a dry mouth are smoking, high amounts of caffeine, certain types of medicines and illnesses that affect salivary glands. It is important to note that sugary drinks are to be avoided in order to relieve the symptoms caused by a dry mouth. This will lead to rapid tooth decay and also gum problems such as paining gums. We recommend adequately hydrating your body and your mouth with water. If symptoms persist, talk to your local dentist or your hygienist to understand underlying causes. 

Is Nitrous Oxide safe?

Nitrous oxide is very safe, because it's easy to take and mild. Nitrous oxide is not addictive. While inhaling nitrous oxide, you remain fully conscience and aware of your surroundings. After coming off of the gas, the effects of it are gone.

If you have respiratory problems or other breathing problems, such as asthma, you should talk with your dentist to see if you are a candidate for nitrous oxide.

Six steps to follow before taking your child to the dentist!

I have a special interest in children's dentistry and recommend taking the following steps before your first visit to the dentist:

1. Talk honestly with your child in a positive and easy tone about going to the dentist before your dental visit.

2. Bring your child to the dental appointment to familiarise with the sight and sounds of the office.

3. Let your child sit in the dental chair and see the instruments the dentist will use to examine their teeth.

4. Give the child an opportunity to ask questions and answer any questions as truthfully as possible.

5. Use clever fun words to de-mystify the examination process. For example, say teeth are getting "counted" rather than examined, or that teeth are being "tickled" when they are been checked, cleaned or polished. Needles are not the favourite thing of anyone, but "putting teeth asleep" will help to avoid any associated pain. This will prepare your child for the visit in a less scary and clinical manner.

6. Never tell your child that "it won't hurt" or "I had bad experience and hate dentists". While you do not want to create an association between going to the dentist and pain, you certainly do not want to mislead your child into thinking that there will not be same possibility for discomfort. Be truthful and don't gloss over that fact that some procedure may be uncomfortable.

What Is Nitrous Oxide?

Nitrous Oxide is a gas that's combined with Oxygen to produce a calming effect and a sense of wellbeing when inhaled. Many dentists use Nitrous Oxide to help a patient relax during dental treatments. When the dental procedure is over, the dentist will have the patient breathe only Oxygen for a few minutes to eliminate the effects of the Nitrous Oxide.

Unlike other sedations, the patient should have a clear head within minutes of coming off of the Nitrous Oxide allowing them to function normally with no lingering effects. Nitrous Oxide is also known as laughing gas.
