Dental Caries: How They Are Formed and What You Can Do to Prevent Them

Dental caries (cavities) are the most common form of oral disease known to man, and the process of getting caries is called tooth decay.
Tooth decay is the destruction of your tooth enamel -- the hard, outer layer of your teeth. This issue can affect children, teens and adults. Plaque, a sticky film of bacteria, is constantly forming on your teeth. When you eat or drink foods or beverages containing sugars, the bacteria in plaque produce acids that attack tooth enamel. The stickiness of the plaque keeps these acids in contact with your teeth, and over time the enamel can break down, according to the American Dental Association (ADA).

The types of caries formed can be broken down into two major groups:

Pit and fissure caries. These are found most often on the chewing surfaces of the back (molar and premolar) teeth, and the back of the front (anterior) teeth. Your teeth are composed of several sections of enamel, and where these sections meet, pits and grooves can trap plaque, causing decay. The proper application of pit and fissure sealants, a hard plastic material applied to seal the grooves and pits when the teeth have erupted, can prevent this type of dental caries. The sealants also make it less likely that you will need restorations (fillings) on those surfaces of the teeth.

Smooth surface caries. These are found most often along the gumline or where two teeth touch (interproximal or the space between teeth), if plaque forms in those areas. With the proper use of dental floss, you can prevent most smooth surface caries in the interproximal area, and using a manual or power toothbrush along the gumline can prevent caries in that area as well.

What is Dry Mouth?

What is Dry Mouth?
Dry mouth means you don't have enough saliva, or spit, to keep your mouth moist. Everyone has a dry mouth once in a while, especially if you're nervous, upset or under stress. But if you have a dry mouth all or most of the time, it can be uncomfortable and can lead to more serious health problems or indicate that a more serious medical condition may exist. That's because saliva does more than just keep the mouth wet -it helps digest food, protects teeth from decay, prevents infection by controlling bacteria in the mouth, and makes it possible for you to chew and swallow.

There are several reasons that the glands that produce saliva, called the salivary glands, might not function properly. These include:

• Side effects of some medications - over 400 medicines can cause dry mouth, including antihistamines, decongestants, pain killers, diuretics and medicines for high blood pressure and depression.
• Disease - diseases that affect the salivary glands, such as diabetes, Hodgkin's, Parkinson's disease, HIV/AIDS and Sjogren's syndrome, may lead to dry mouth.
• Radiation therapy - the salivary glands can be damaged if your head or neck are exposed to radiation during cancer treatment. The loss of saliva can be total or partial, permanent or temporary.
• Chemotherapy - drugs used to treat cancer can make saliva thicker, or "ropey," causing your mouth to feel dry.
• Menopause - changing hormone levels affect the salivary glands, often leaving menopausal and post-menopausal women with a persistent feeling of dry mouth.
• Smoking - many pipe, cigar and heavy cigarette smokers experience dry mouth.

Dental Veneers: Pros and Cons

Dental veneers are thin pieces of tooth-colored porcelain cemented to the front surfaces of your natural teeth, and are an easy way to address a variety of physical and aesthetic problems. Because they're also permanent, however, you'll need to carefully weigh the pros and cons of the procedure before you decide to get them. Here are six things to think about and discuss with your dentist.

Pro #1: Easily Whiten Your Smile
Years of drinking coffee, smoking cigarettes or eating highly pigmented foods eventually take their toll on your teeth, turning them an unattractive shade of yellow or brown. Stained enamel can be bleached at home or by your dentist, but it can become stained again. If you're looking for an easier way to whiten your smile for good, dental veneers may be a good fit for you. Veneers are largely stain-resistant, according to the National Institutes of Health (NIH), so you won't have to worry about discoloration or needing to have your veneers whitened.

Crowns

A crown is a tooth-shaped cover placed over a tooth that is badly damaged or decayed. Many people call it a cap.
Crowns may be placed for several reasons. Usually the tooth has been broken or severely damaged by decay. As a result, a filling can't replace enough of the tooth or make the tooth strong enough. A crown may hold together parts of a cracked tooth. It also can be used to hold a bridge in place. Crowns can be used to improve appearance as well. They may be placed to cover misshapen or badly discolored teeth.

Crowns can be made ahead of time (prefabricated) or made to order in a laboratory. Prefabricated crowns are made of plastic or stainless steel. They can be used on a temporary basis until a permanent crown is made.

Crowns can be made of:

• All metal
• Zirconia
• Porcelain fused to metal (PFM)
• Porcelain fused to zirconia
• All ceramic

Metals include gold alloy, other alloys (palladium) or a base-metal alloy (nickel or chromium). The all-metal or PFM crowns are stronger and are better choices for back teeth than ceramic crowns. PFM and all-ceramic crowns are the same color as your natural teeth. They look just like normal teeth.
