What is plaque and how does it affect your teeth?

Plaque is a sticky film of bacteria that covers our teeth and, when we eat something, these bacteria release acids that attack the tooth enamel.

When these attacks are repeated over time, the enamel will break down and this will eventually lead to cavities.

When plaque is not removed through daily brushing and cleaning it hardens into calculus or tartar. When tartar collects above the gum line, brushing and cleaning between the teeth becomes more difficult.

The gum tissue can become swollen or may bleed. This is called gingivitis and it is the early stage of periodontal (gum) disease.

There are several steps you can take to protect yourself against this happening:

– Brush your teeth twice a day with fluoride toothpaste
– Clean between teeth daily with floss or an interdental cleaner
– Eat a balanced diet and limit the number of snacks between meals
– Visit your dentist regularly for professional cleanings and oral exams
– Ask your dentist about sealants – these are protective coatings that can be applied to the back teeth where decay often starts.

If you take steps to remove the plaque each day, you have a greater chance of avoiding tooth and gum problems.

The secrets of avoiding gum disease as an older adult

Gum disease also known as periodontal disease often progresses slowly, without pain, over a long period of time and that’s one reason it is common among older adults.

The longer the disease goes undetected and uncontrolled, the more damage it causes to gums and other supporting tissues.

Although periodontal disease is caused by plaque, other factors can increase the risk or severity of the condition, including:
– Food left between the teeth
– Tobacco use smoking and smokeless tobacco
– Badly aligned teeth
– Ill-fitting bridges or partial dentures
– Poor diet
– Systemic diseases such as anemia

Although periodontal disease is common, it can be controlled and, if caught in its early stages, it can be reversed. However, in advanced stages, it may require surgery.

Look out for the following warning signs and see your dentist if you notice any of them:
– Bleeding gums when you brush
– Red, tender or swollen gums
– Gums that have pulled away from the teeth
– Pus between your teeth and gums when the gums are pressed
– Loose teeth or teeth moving apart
– Any change in your bite
– Any change in the fit of your partial dentures
– Constant bad breath or bad taste

Keeping an eye out for these problems and having regular dental checkups can help you stop gum disease becoming a major and expensive problem.

What Causes Sensitive Teeth?

 If you sometimes find the taste of something hot or cold painful on your teeth, you may suffer from sensitive teeth.

Sensitive teeth is a common problem which may be caused by cavities and fractured teeth.

But it can also be caused by worn tooth enamel, a cracked tooth or an exposed tooth root.

Tooth enamel is the strongest substance in the body and it protects the crowns of healthy teeth. A layer called cementum protects the tooth root under the gum line.

The part underneath the enamel and the cementum is called dentin, which is less dense than enamel or cementum.

The dentin contains small hollow tubes or canals called tubules. When the dentin loses its protective covering, the tubules allow hot, cold, acidic or sticky foods to reach the nerves and cells inside the tooth.

This causes hypersensitivity and occasional discomfort but fortunately, the irritation does not cause permanent damage.

Following proper oral hygiene helps prevent the gums from receding and causing the pain of sensitive teeth.

Brushing your teeth incorrectly or even brushing too much can cause gum problems.

Your dentist will advise you on the best daily routine to maximize your oral hygiene.
