Tooth Sensitivity & Desensitisation
Sharp discomfort from cold, heat, sweetness or brushing deserves more than a sensitive-tooth toothpaste — first, we work out why it is happening.
Why are my teeth sensitive?
Sensitivity often occurs when dentine — the layer beneath the enamel — becomes exposed or more easily stimulated. However, similar symptoms can also occur with decay, cracks, leaking restorations or problems involving the dental pulp, which is why persistent or new sensitivity should be assessed.
Possible contributors include
- Gum recession and exposed root surfaces
- Enamel wear or erosion
- Overly aggressive brushing
- Tooth grinding or wear
- A cracked or decayed tooth
- Recent dental treatment in some cases
Treatment depends on the cause
After assessment, management may include changes to brushing technique and home-care products, professionally applied desensitising or fluoride products, sealing or bonding exposed areas, or treatment of an underlying dental problem.
The aim is not simply to suppress the symptom but to identify and manage the reason the tooth has become sensitive.
When should sensitivity be checked promptly?
Arrange an assessment if sensitivity is new, worsening, limited to one tooth, occurs without an obvious trigger, lingers after hot or cold exposure, or is accompanied by pain when biting, swelling or other symptoms. These patterns may indicate something other than routine dentine sensitivity.
