Chlorhex is way less damaging than hydrogen peroxide. You should never put hydrogen peroxide on s cut unless there is debris in it. Hydrogen peroxide actually damages white blood cells and lessen the path to healing. Chlorhexidine sol. Is not systemic so it won't absorb in to your blood stream. Just be sure to rinse well w h2o after to avoid swallowing.
U hv to wait till second trimester a must Im a dental hygienist not safe now
Also the chlorhexidine rinse does work well but I wouldn't use it being pregnant at least not until the second trimester and probably not even then. So much is absorbed into the body through the mouth. Even if you dont swallow it.
Look for peroxyl it is a mouth wash made with hydrogen peroxide it should be perfectly safe to use while pregnant or just use hydrogen peroxide mixed with water the peroxyl has a minty flavor. You can use it twice a day. Try sensodyne toothpaste you can use it all the time. And of course floss if you dont already if you find it difficult to floss there is floss with handles and they also make these proxy brushes that go in between the teeth which are amazing! Having worked as a dental assistant the dentist is correct in waiting until your second trimester a lot of bacteria will be brought up with the root planning and scaling which could bring bacteria to the placenta and baby. I would ask both your obgyn and dentist if you need antibiotics before the root planning as a precaution. Most times its not necessary but because you are pregnant it is worth asking about. You would take one dose an hour before your appt.
I had dental work done when I was about 9 weeks and used the chlorexidine gluconate for two weeks after.
As long as your not swallowing it I don't think it would hurt the baby since you can use it to clean cuts on your hands ect
i'd use what the dentist recommended - you want will work best, an infection would be dangerous - then you would have to take more drugs
