as the baby is two years its important to save the dentition for the upcoming permanent tooth consult the dentist soon for treatment

Consult dentist. They do examination  and tell you what to do. Milk teeth are also important  so plz save them.

Hello dear! In accordance to your description I assume your baby is experiencing teething pain. Massage your baby's gums in circular motion where you can see erupting teeth with Pansoral teething gel for 3-4 times a day I expect that your baby will be comfortable once teeth are erupted completely. But it's always better to rule out any possibility of cavity causing pain. So do visit a dentist.

You can give peadiatric dose of painkiller syrup,also make sure to see a doctor

Do consult to pediatric dentist. Many of times it's a just a teething pain. Without any delay conlust pediatric dentist.
