Amalgam fillings are not advisable anymore, infact they are banned in several countries. If you do not have any pain, you can get those removed, get the Composite or GIC restorations done. Do not wait for long as the amalgam fillings cause micro leakage and can decay the tooth from inside.
Next Steps
Visit a Dentist and get the re restorations done.
Health Tips
Brush your teeth twice a day, and as you are in your first trimester, do not take any medicine by yourself if there’s a toothache. It’s better to consult a Dental surgeon and get the treatment done.
