Yes, it is ok for you to see a dentist just before your due date. Especially if you have gum disease before pregnancy, there is a huge chance you’d still have it. There is absolutely no harm in seeing a dentist during pregnancy and it does not affect the baby, in fact, oral healthcare such as X-rays, local anaesthesia, and teeth cleaning has been proven to be completely safe during the trimester days.Adding to this, make sure to not put off these dental treatments for dental issues. If truly necessary, you can take the local anaesthetics like lidocaine as they are safe to use during pregnancy, similarly if you take antibiotics, however, always make sure to check with your doctor, irrespective of it all.
