  • When their tooth begins erupting, you can help sooth the gums by rubbing it gently with a moist cloth or gauze. You can also let them use a teething ring to help alleviate the discomfort they feel during the eruption of their teeth.

  • Although primary teeth are not permanent, they are still important to the development of the permanent teeth. These also contain dentin, nerves, pulp, blood vessels and root to anchor the tooth to the bone just like what the permanent teeth have.
