Hello mam
If you are having toothache that means the cavity has already reached to the nerve of the tooth or has pus at the end of the roots.As you are
pregnant you may face gum problems in next few months which will cause more pain.Second trimester is the safe period to get the dental treatment done but ofcourse after your gynaecologist gives you a green flag.Get the proper treatment done as your gynaecologist advise.
I would like to add one more thing here that if you have toothache you will avoid having proper food which will affect your and baby's health.You need proper nutrition in this phase.Take care .
Next Steps
Visit your gynaecologist first and let her know about your toothache then with her advise you can visit dentist nearby and get relief from your pain.
