The difference between canker sores and cold sores

Although canker sores are often confused with cold sores, there is a difference.

Canker sores occur inside the mouth, and cold sores usually occur outside the mouth.

Canker sores are small ulcers with a white or gray base and a red border. There can be one or more sores in the mouth. They are very common and often recur.

They usually heal in a week or two and rinsing with antimicrobial mouthrinses may help reduce the irritation.

Cold sores – also called fever blisters – are composed of groups of painful, fluid-filled blisters that often erupt around the lips and sometimes under the nose or chin.

Cold sores are usually caused by herpes virus type I and are very contagious. They usually heal in about a week.

Over-the-counter topical anesthetics can provide temporary relief and prescription antiviral drugs may reduce these kinds of viral infections.

Is bottled or tap water better for your teeth?

With many people concerned about the taste and purity of tap water, the sales of bottled water have increased significantly in recent years.

Tap water goes through a process of purification designed to eliminate suspended materials, remove tastes and odors and kill microorganisms.

Fluoride is added to most tap water supplies with the aim of reducing cavities.

Fluoride becomes incorporated into our teeth as they develop and makes them more resistant to decay. It can reverse the progress of early cavities and reduce the need for dental treatment.

Mass water fluoridation has played an important role in reducing tooth decay.

The problem with bottled waters is that they usually don’t contain fluoride.

So there is a risk that drinking bottled water can increase the risk of cavities for some people.

If you drink a lot of bottled water, you can make up for this by using fluoride toothpaste and mouth rinse.

Your dentist may even suggest a fluoride supplement if they notice an increase in cavities.

What's involved in getting a dental implant?

Dental implants are increasingly popular as a way to replace missing or damaged teeth.

Their great advantage is that they look natural and feel secure helping you to restore your smile and eat more easily.

Implants are an ideal solution for many people but they are not an option for everyone.

Placing implants requires some surgery so patients must be in good health, have healthy gums and have adequate bone to support the implant.

They must also be committed to taking action to maintain their oral hygiene and to visiting the dentist regularly.

The process for placing implants is as follows:

First, surgery is performed to place the anchor. This can take up to several hours. Following the surgery, you may need to wait up to six months for the bone to grow around the anchor and firmly hold it in place. Sometimes follow up surgery is required to attach a post to connect the anchor to the replacement teeth. Alternatively, the anchor and post may already be attached and are placed at the same time.

After the gums have had several weeks to heal, the next step is to fit specially-made artificial teeth to the post portion of the anchor. This can take a few weeks to complete as several fittings may be required.

Implant surgery can be done either in a dental office or in a hospital, depending upon a number of factors. A local or general anesthetic may be used. Usually pain medications and, when necessary, antibiotics are prescribed.

After your implants are fitted, your dentist will give you tips and advice on maintaining your oral hygiene.

Your dentist can help you decide whether you would be a good candidate for implants.

Is it safe to have an X-ray while pregnant?

Some women worry about whether its safe to have an X-ray exam while they are pregnant.

This can cause them to put off treatment they need.

However, untreated dental infections can pose a risk to the fetus, and dental treatment may be necessary to maintain the health of the mother and child. Sometimes this will mean an X-ray is necessary.

Radiation from dental X-rays is extremely low but every precaution is taken to minimize radiation exposure.

For example, a leaded apron reduces exposure to the abdomen and should be used when a dental radiograph is taken.

In addition, a leaded thyroid collar can protect the thyroid from radiation, and should be used whenever possible. The use of a leaded thyroid collar is strongly recommended for women of childbearing age, pregnant women and children.

Overall there is no reason to avoid dental radiographs (X-rays) while pregnant, breastfeeding or trying to become pregnant.

Follow your dentists advice and ask questions if you have any concerns.
