Dental plaque – what it is and how to avoid it

You’ve probably heard people talking about plaque and maybe you’ve some idea of what it is.

But it’s useful to know a bit more about it so that you can do what’s necessary to minimize the risks.

Plaque is a sticky film of bacteria that forms on teeth and gums.

When you’ve eaten a meal or snack, the bacteria in plaque release acids that attack tooth enamel. When this happens regularly, the enamel can weaken. This eventually leads to tooth decay.

The food we eat often causes plaque bacteria to produce acids. So, if you eat a lot of snacks, your teeth may be suffering acid attacks all day.

If you don’t remove the plaque through effective daily brushing and cleaning between the teeth, it can eventually harden into calculus or tartar.

Another effect of plaque is that it also produces substances that irritate the gums, making them red and tender or causing them to bleed easily.

If you want to prevent tooth decay and gum disease, make sure you have a balanced diet and avoid having too many snacks between meals.

When you feel like a snack, go for foods such as raw vegetables, plain yogurt, cheese or a piece of fruit.

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.

Why cavities aren’t just for kids

Tooth decay or cavities result from destruction of the tooth enamel and can lead to a range of problems from toothache to bad breath.

Cavities occur when foods containing carbohydrates (sugars and starches) such as milk, sugared drinks, cakes or candy are frequently left on the teeth.

Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.

Many people associate cavities with children but the changes that occur with aging make cavities an adult problem, too.

Recession of the gums away from the teeth, combined with an increased incidence of gum disease, can expose tooth roots to plaque.

Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.

Decay around the edges of fillings is also common to older adults. As many of them did not benefit from fluoride and modern preventive dental care when they were younger, they often have a number of dental fillings.

Over the years, these fillings may weaken, fracture and leak around the edges.

Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.

You can help prevent tooth decay by following these tips:

– Brush twice a day with fluoride toothpaste
– Clean between your teeth daily with floss or interdental cleaner
– Eat nutritious and balanced meals and limit snacking

It’s also worth asking your dentist about supplemental fluoride, which strengthens your teeth, and about dental sealants, a plastic protective coating which is applied to the chewing surfaces of the back teeth to protect them from decay.

In addition, it’s important to visit your dentist regularly for professional cleanings and oral examination.

Fixing crowded and crooked teeth with orthodontics

Correcting problems with crowded and crooked teeth not only gives you a better smile, it also leads to a healthier mouth.

Malocclusion, also known as “bad bite”, involves teeth that are crowded or crooked.

Sometimes, the upper and lower jaws may not meet properly and, although the teeth may appear straight, the individual may have an uneven bite.

Problems such as protruding, crowded or irregularly spaced teeth may be inherited. But thumb-sucking, losing teeth prematurely and accidents also can lead to these conditions.

As well as spoiling your smile, crooked and crowded teeth make cleaning the mouth difficult. This can lead to tooth decay, gum disease and possibly tooth loss.

A bad bite can also interfere with chewing and speaking, cause abnormal wear to tooth enamel and lead to problems with the jaws.

Orthodontic treatment can help correcting these problems giving you a better smile but, more importantly, creating a healthier mouth.

Your dentist will advise you on how orthodontic treatment could help you.

Common mouth sores: causes and cures

Mouth sores can be very annoying and painful and can have many causes.

The causes can range from infections – bacterial, viral or fungal – to a loose orthodontic wire or a denture that doesn’t fit or a sharp edge from a broken tooth or filling.

But mouth sores may be symptoms of an underlying disease or problem.

So, if you’ve had any mouth sore that lasts a week or longer, it’s a good idea to get your dentist to check it out.

Here are some of the most common mouth sores:

Canker sores: These are small ulcers with a white or gray base and a red border. They appear inside the mouth and are not contagious though they often return. Problems such as poor immune systems, viruses or fatigue and stress may be involved. They usually heal on their own after a week or two.

Cold sores: Cold sores are annoying and painful. They are also known as fever blisters or Herpes simplex and are groups of fluid-filled blisters. They often erupt around the lips and sometimes under the nose or around the chin. Cold sores caused by herpes virus type 1 are very contagious and the virus stays in the body. Cold sore blisters usually heal in a week by themselves.

Candidiasis: This fungal infection (also called moniliasis or oral thrush) occurs when the yeast Candida albicans reproduce in large numbers. It is common among denture wearers and people who have dry mouth syndrome are very susceptible to it. The focus is on preventing it or controlling the conditions that caused the outbreak.

Any mouth sores that last more than a few days should be checked with your dentist.

How cosmetic dentistry can change your smile – and your life

Modern cosmetic dentistry has created many opportunities that did not exist before for people to improve their appearance and change the way they feel about themselves.

Although cosmetic dentistry really did not exist a few yaears ago, it now attracts interest from a wide range of people.

There are few people who don’t want to improve their appearance by making their teeth straighter and whiter so that they look better when they smile.

New technology and procedures have created many more opportunities for dentists to help patients look better.

One of the most important opportunities for doing this is porcelain veneers.

These are custom-made wafers that the dentist places over the front of the teeth to repair damage and make them look better.

They can overcome many cosmetic dental problems such as whitening stained or discolored teeth, closing gaps between teeth or correcting a crooked smile without the need for braces.

They can also cover up chips and imperfections so that the smile looks much better.

Another important cosmetic trend is the increased use of white fillings.

White fillings now are more lifelike than ever and they last longer than previously.

They have become the material of choice for many dentists as they blend in with teeth and look better.

If you feel your smile is less than perfect, talk to your dentist about how it could be better.

How sugar in your diet affects your teeth

The sugar content in the food you eat has a big effect on your teeth and gums.

When bacteria (plaque) come into contact with sugar in the mouth, acid is produced, which attacks the teeth for 20 minutes or more. This can eventually result in tooth decay.

That’s why drinking sugar-filled sodas, sweetened fruit drinks, and non-nutritious snacks can take a toll on teeth.

This is particularly true for children as their eating patterns and food choices affect how quickly they develop tooth decay.

Foods that contain sugars of any kind can contribute to tooth decay. However, almost all foods, including milk or vegetables, have some type of sugar. Many of them also contain important nutrients that are an important part in our diet.

To help control the amount of sugar you consume, read food labels and choose foods and beverages that are low in added sugars. Soft drinks,candy, cookies and pastries often contain added sugars.
