| Using the Smell Checker |
| Methyl mercaptan is the chemical culprit found in the worst cases of bad breath.
A new sensor, claimed to be twice as sensitive as the human nose, may eventually be available to alert people to a bad case of halitosis. The device contains an enzyme that reacts only to methyl mercaptan. It is small enough that the developers think it could fit into a cell phone for discreet breath checks.
Because bad breath can also signal gum disease, the device may also help dentists identify patients in need of additional oral care. Although bad breath can occur in healthy mouths, people with bleeding gums are vulnerable to additional health complications. A tool that detects the presence of methyl mercaptan will help dentists identify problems earlier.
It may be a while before the new sensor becomes available. Meanwhile, Dr. Richard Price, a representative of the American Dental Association, advises cleaning your mouth as a simple and direct method of addressing bad breath. Brushing your teeth and tongue clears out bacteria where they love to hide.
For those plagued with bad cases of halitosis, Dr. Price recommends using a tongue scraper in the morning and evening. A small plastic tool available at drug stores, the scraper can be used along the length of the tongue to loosen and help remove bacteria.

| Back to School Reminders
|
As you purchase school supplies for your child this school year, think about how you can also support healthy dental habits during school hours.
Do you buy healthy snacks for your child to eat on breaks? Raisins, milk in single-serving cartons, raw nuts, and fresh fruit are excellent energy boosters without harmful sugars in them.
Chances are, the school's water supply is fluoridated. But do you know that for certain? If it isn't, consider making fluoridated bottled water a routine part of your child's lunchbox.
Remember that the American Dental Association recommends brushing twice a day and daily flossing.

| About Sensitive Teeth |
There are several causes of tooth sensitivity: cavities, fractured or cracked teeth, worn tooth enamel, exposed tooth roots. If you have regular checkups, these issues are likely to be detected early.
Naturally occurring enamel protects the teeth and cementum protects the roots. The underlying dentin is a less dense system of microscopic tubes and canals. If the enamel or cementum is reduced, heat and cold more easily stimulate the nerves and can cause sensitivity.
If you are suffering from sensitivity, the first step is to review proper brushing technique and try a desensitizing toothpaste. If it continues, make an appointment to come in for an assessment. In some cases, fluoride gels can strengthen tooth enamel and bonding agents can seal problem tooth roots.
