Gum Sensitivity and Periodontal Disease
When it comes to periodontal disease, resist the temptation to avoid brushing teeth that are sensitive to cold. Gum disease will always make teeth more susceptible to cold temperatures. It just becomes worse if you try to avoid them.
Any dental procedure might cause sensitivity in the teeth afterward. To let you know they've been harmed, this is what they'll do. Injuries to the nerves in a tooth, such as a tooth cavity, may cause pain. If the teeth are maintained clean, this should not last too long. The sensitivity will persist or worsen if the teeth are not cleaned regularly.
Consult your dentist if your teeth are very sensitive. These symptoms may indicate the need for root canal therapy, gum tissue grafts, desensitizing toothpaste (including potassium nitrate), or a concentrated fluoride gel (0.4 percent stannous- or 1.1 percent sodium-fluoride).
