Question:
Acute HyperSensitive Teeth: I suffer with acute hypersensitivity in most teeth.
I use Gel-kam and Macleans remineraling toothpaste and wear mouthguards to stop grinding. I have had desensitising agents put on my teeth making little to no difference.
I have been suffering from this for over two years and I am frustrated by my dentist's lack of solutions saying that a root canal is too drastic as it would mean taking the nerves out of most of my teeth. ...Visitor from Worcester England UK
Answer:
Let's first talk about what causes sensitvity. Sensitivity can occur when there is decay present or when teeth have had restorations placed. It can also occur as a result of abrasion, erosion, or attrition of the enamel or cementum which covers the root surface.
Without getting into too much detail, decay and placing restorations (especially large ones) can irritate the pulpal tissue resulting in sensitivity. Oftentimes after the placement of bonded composites or veneers teeth will become sensitive from the acid etchant. However, this sensitivity usually goes away.
Since you say you are a tooth grinder, I would guess that you also have some gum recession which exposes the roots of your teeth. Vigorous brushing can wear away tooth structure on the roots. Bruxism can also cause breakdown of the root surface.
If you have an acidic diet, the acid can weaken the enamel on the biting surfaces of your teeth. This weakened enamel can break away leaving little pot holes, especially if you are a grinder. The exposed underlying dentin creates sensitivity. You could try repairing those eroded areas.
Unfortunately, if the sensitivity is affecting your quality of life and is that unbearable, root canal treatment would be indicated. I would definitely address your bruxism issue and evaluate your bite. Hope this has helped.
