A small crack in the tooth is capable of causing tooth sensitivity. The crack will then enlarge and grow deeper into the root causing obvious pain.
Key takeaways:
– Take good care of tooth enamel which is the protective layer. Worn out enamel exposes nerve endings leading to pain.
– Brush softly with a soft bristled brush to avoid wearing out tooth enamel.
– Teeth sensitivity could be a sign of other problems such as receding gums, teeth grinding and gum disease.
Ignoring your teeth can make things worse. Brush and floss twice a day to help keep your smile bright and pain-free. And see your dentist for a checkup twice a year.
