desensitising agent

by Dr Peter Norton, Dental On Clarke, Crows Nest, NSW 

This desensitising agent is designed for use on teeth that are sensitive to cold or sweet foods. I find it works particularly well on exposed root surfaces when there has been some gingival recession, as well as some cervical abrasion lesions. 

What’s good about it? 

Super Seal is probably the most effective and easy-to-use desensitising agent I’ve tried. It can be rubbed on cervical tooth structure and it doesn’t damage or traumatise the soft tissues. There’s no discernible coating that the patient can feel on their gums. 

It doesn’t need to be light cured so it’s all very easy. It can be applied to a wet or dry tooth but I like to do some air-drying, after warning those patients with very sensitive teeth that some air is coming. It’s applied with a microbrush or a cotton pellet that’s been soaked in the Super Seal. Then, a gentle spray of air from a distance of about 13 to 18 centimetres. You have to be careful not to blast the material off the tooth; you’re just distributing it. If a tooth is very sensitive, I apply two to four coats with gentle air in between coats.

For many patients, it gives virtually instantaneous relief. I work part-time in cool-climate NSW. I’ve found that tooth sensitivity fluctuates with the seasons, but Super Seal has allowed me to do scaling and cleaning without local anaesthetic throughout the year. 

What’s not so good? 

It doesn’t work for everyone. If there is irreversible pulpitis, caries or a very deep abrasion lesion, you’ll need other methods.
