The third molars, called “wisdom teeth” because they usually become visible when a person is 17 to 25 — supposedly the time we achieve wisdom, may have adverse effects on adjacent teeth. Most adults have four wisdom teeth, although some people have more; and some, none at all. The wisest thing to do about wisdom teeth may be to have them removed if they are poorly positioned.
What is an impacted wisdom tooth?
If a wisdom tooth is pushing against gums, other soft tissues, or adjacent teeth at an awkward angle, it is referred to as “impacted.” Usually this occurs when there is not have enough room in the jaws for these last molars to fit next to their adjacent teeth. They can disrupt the gum tissue attachment of their neighboring teeth and the surrounding bone leading to periodontal disease and, ultimately, their loss.
In many cases, impacted teeth are painless, and those who have them have no warning of the problem. Thus it is important to have routine dental exams during the time when the third molars are coming in.
When should wisdom teeth be removed?
It is better to remove wisdom teeth early rather than waiting until periodontal (gum) disease has set in. As individuals age, keeping their wisdom teeth may lead to more serious problems. Periodontal defects tend to get worse in the presence of retained third molars. Furthermore, there is a higher incidence of postoperative symptoms in people over 25.
What are the pros and cons?
Removing impacted third molars can have a negative influence on the periodontal tissues of adjacent second molars. A number of techniques, such as scaling, root planing, and bacterial plaque control, can be used to minimize periodontal problems and promote healthy healing.
Surgical removal of wisdom teeth will involve some mild to moderate post-operative discomfort. Use of aspirin or ibuprofen for a few days after surgery will provide pain relief and control most swelling and symptoms. Antibiotics may be prescribed to ensure infection-free healing. It is important to keep the socket area clean by washing and rinsing with saline or antibacterial rinses. Careful surgery will promote good healing with minimal periodontal consequences to adjacent second molar teeth.
To decide whether your wisdom teeth should be removed, you will need an evaluation to assess the clinical health of the wisdom teeth, the neighboring teeth, and other vital structures. X-ray and digital imaging techniques play an important role in determining the exact position of the wisdom teeth in the jaw. A full assessment and consultation will include all the risks, benefits, likely consequences, and alternative treatment options. This will provide you with the wisdom you need to determine what is best for your wisdom teeth.

The medical term for dry mouth is xerostomia (“xero” – dry; “stomia” – mouth), something that many of us have experienced at some point in life. However, for some people it can be a chronic condition that is ideal for promoting tooth decay. It can also be a warning sign of a more serious health condition.
Dry mouth occurs when there is an insufficient flow of saliva, the fluid secreted by the salivary glands. Your major salivary glands are located in two places: inside the checks by the back top molars and in the floor of the mouth, with about six hundred tiny glands scattered throughout your mouth. And many people are surprised to learn that when they are functioning normally, saliva glands secret between two and four pints of saliva per day! While this may sound like a lot (and it is), saliva is key for buffering or neutralizing acids in the mouth. Without this powerful protection, tooth decay can increase quickly. This is especially true for older individuals who have exposed tooth root surfaces.
It is also important to note that there are times when mouth dryness is perfectly normal. For example, when you wake, you will probably have a slightly dry mouth because saliva flow slows at night. Another example is if you are dehydrated when it is simply a warning sign that you need to drink more fluids (especially water). Other causes for temporary dry mouth include stress as well as what you consume: coffee, alcohol, onions, and certain spices.
You can also have a dry mouth due to a side effect from an over-the-counter (OTC) or prescription medication. If it turns out that this is the cause in your case, you need to talk to the prescribing physician to see if there is something else you can take to avoid this side effect. If there are no substitutes, one tip you can try is to take several sips of water before taking the medication followed by a full glass of water, or chew gum containing xylitol, which moistens your mouth and decreases the risk of tooth decay.
Another cause of dry mouth is radiation treatment for cancer in the head and neck region. Yes, these treatments are crucial for fighting cancer; however, they can inflame, damage or destroy salivary glands. You can also have dry mouth from certain systemic (general body) or autoimmune (“auto” – self; “immune” – resistance system) diseases, diabetes, Parkinson's disease, cystic fibrosis and AIDS (Acquired Immune Deficiency Syndrome).
