Tooth sensitivity symptom cause and home care
Tooth sensitivity usually reflects exposed dentine, but decay, cracks, and pulp inflammation must be excluded.
What usually causes tooth sensitivity and what must be excluded?
Tooth sensitivity usually reflects exposed dentine, but decay, cracks, and pulp inflammation must be excluded.
Why can recession or enamel wear expose dentine tubules?
Dentine tubules can transmit fluid movement toward the pulp; recession, enamel wear, erosion, or a crack can expose them.
What home care can help protect sensitive teeth?
Use a soft brush, gentle pressure, fluoride toothpaste, and reduce acidic exposure; worsening localised sensitivity needs attention.
Which sensitivity symptoms should a dentist examine?
See a dentist for spontaneous or lingering pain, pain on biting, a visible crack, swelling, or sensitivity in one restored tooth.
What should your dentist check before recommending treatment?
Ask whether dentine is exposed, whether decay or a cracked filling is present, and whether fluoride treatment or bonding is suitable.
Frequently asked questions
Why is one tooth suddenly sensitive?
A cavity, crack, leaking restoration, recession, or pulp inflammation can affect one tooth and needs examination.
Can sensitive toothpaste repair enamel?
It can reduce stimulus transmission or nerve response, but cannot restore lost structure or seal a crack.
