People sometimes confuse canker sores and cold sores, but they are completely unrelated. Both can be painful, but knowing the differences can help you keep them in check.

A canker sore is typically one that occurs on the delicate tissues inside your mouth. It is usually light-colored at its base and can have a red exterior border.

A cold sore or fever blister, on the other hand, usually occurs on the outside of the mouth, usually on or near the nose or lips. A cold sore is contagious because it is caused by the herpes simplex virus, and it is usually painful and filled with fluid.

In most cases, patience is the best medicine for treating canker sores. A healthy diet and good oral hygiene are usually the best remedy, but some special rinses and anesthetics can help. Cold sores can be treated effectively with some over-the-counter topical creams; sometimes, an antiviral medication will be prescribed by your doctor.


Laser Use In Dentistry:

Most small cavities can be completed without numbing using a laser. The WaterlaseMD Laser can be used to numb the large majority of teeth by simply shining the low power laser light on the tooth. Then, at a higher setting, the laser can be used to get the cavity out of the tooth, or a regular dental drill can also be used. We have been using the laser in the office for 6 years now and nearly all the patients report the same when asked: "On a scale of 1-100, with 100 being very uncomfortable, how do you rate the laser just used?"

  • I didn't feel a thing, I rate it zero discomfort.

  • All I felt was some cold, maybe a two or a three.

  • I didn't feel a thing, this is great, no pain at all.

  • This is great, I really don't like being numbed up.

We have found that people do not like the feeling of being numb, and the laser is a great tool to get their small fillings done, pain-free without numbing.
