Do you have sensitive teeth or know someone who does? St. Lawrence Dentistry offers very effective treatments for this common issue.
Some peoples teeth are sensitive by virtue of the fact that they have larger than average nerves in their teeth. At the center of the tooth is the pulp tissue which is mostly nerve tissue. In general the bigger the pulp space the less thick the side walls are to protect the pulp and the more sensitive your teeth can be. Younger people tend to have larger pulp spaces and also larger dentin tubules. These tubules are the pores of the tooth leading toward the pulp. This is why people with large nerves in their teeth can have perfect looking teeth yet they are sensitive.
The leading cause of tooth sensitivity is gum recession which is gradual exposure of the root of the tooth caused by loss of the gum (gingival tissue). Some gum recession is related to genetics and how the tooth erupted in the dental arch when you where a child. There is also a correlation between orthodontic treatment and tooth recession. One factor that patients can control to help stop gum recession is to make sure they are brushing gently and with a soft tooth brush. Hard brushing can also wear away your enamel which can further exacerbate tooth sensitivity. Habits such prolonged use of hard mouth mints can also contribute to gum recession. In addition, chewing tobacco can cause the gum to degenerate and recede.
If you have receding gums you should pay close attention to which type of tooth paste you are using. Although whitening, and tartar control toothpastes are great for many patients they have abrasive components and phosphates which can make your teeth sensitive. If your gums are receded and you have sensitive teeth it is best to use a tooth paste which is gentle on teeth and contain substances which can block the dentinal tubules to reduce sensitivity.
St Lawrence Dentistry offers several different in office treatments for tooth sensitivity. One treatment is GUM Protect Desensitizing Solution (Sunstar Americas Corporation) which provides an immediate onset of action, instantly blocking the dentin tubules inside and out. The Benefits of this product is it easily treats hypersensitive exposed root surfaces. It does so by the fact that its conditioner component removes the smear layer of the tooth to expose the tubule openings allowing liquid to penetrate. This liquid binds calcium and protein molecules in the tubules to provide deep, effective and long lasting tubule plugs.
G-Coat Plus Dental Surface Sealant from GC America Inc. is also an excellent treatment for minimal sensitivity. Sometimes Dr. Hawryluk will use this product and the GUM product described above in a combination procedure. When used in concert the treatment can amplify in effectiveness.
Another treatment is MI paste. This product is the only product for professional use containing RECALDENT™, a special milk-derived protein that releases calcium and phosphate to the surface of the teeth. St. Lawrence Dentistry will often make custom mouth trays to for the patient to wear at home for 10 minutes a day with the MI paste. These trays allow maximum contact of the MI paste with your teeth. Dr. Hawryluk has obtained excellent results with the use of MI paste.
If the sensitive area is also eroded inwards, Dr.Hawryluk can sometimes bond a layer of composite resin on your tooth. This is very strong and provides very effective insulation of the tooth nerve.
Sometimes the sensitive area can be covered up with Gum tissue by using the Pinhole Grafting technique. This is can restore the architecture of your gum to its original form.
