As with everything when expecting a new addition, you will likely experience some changes in your oral health. Don’t worry it’s all been done before. Help and advice are never far away.


The first trimester:

It is best to avoid any elective treatment in this period as your developing baby is the most susceptible to environmental stimulus. It is also when organogenesis (the development of new organs) occurs. If you are or think you may be pregnant and in the first trimester, please tell your dentist so that appropriate management can be ensured. 


The second trimester:

This is the ideal time for a pregnant patient to be seen, including for non-essential treatment. Your comfort as a patient is most manageable during this time and there are no medical contraindications for you or your baby.


The third trimester:

During the second half of the third trimester it is best to avoid non-essential treatment. This is due to the uterus being increasingly sensitive to environmental stresses causing an increased (but still minor) risk of premature birth. Your comfort as a patient at this time is also decreased. Please feel free to ask questions and discuss the management of your dental conditions at this time. We will always be happy to consult with you and manage you accordingly. 


There are several oral conditions that are associated with and modified by pregnancy and the hormonal changes that came along with it. If you are concerned at any time throughout the term pregnancy, please ask us.



A common concern, especially during pregnancy is the need for radiographs. Modern radiography equipment has been proven to be extremely safe. The amounts of radiation that the patient is exposed to during a dental film being taken is minimal and is further explained here (radiograph link). Despite the minimal exposure, we will still provide lead aprons and protective thyroid shields for your peace of mind.


Vertical transmission of oral bacteria:

Academic studies have shown that the bacteria that will populate your child’s mouth throughout their life is transmitted vertically from mother to child. This means that the bacterial load present in your mouth around the time of birth will colonise your babies mouth shortly after birth. Therefore, it is essential that when you are pregnant that you maintain excellent oral health. It will have an effect on your child throughout their life!


Vitamin D and calcium:

Mothers and expectant mothers require adequate calcium and Vitamin D for optimal development of their baby's teeth and bones. Calcium is found in common foods such as milk, cheese, dried beans and leafy green vegetables. Cheese has also been shown to have pH neutralising benefits if eaten after a meal.

Vitamin D is responsible for increasing intestinal absorption of calcium, iron, magnesium, phosphate, and zinc. Calcium is one of the most important elements in building strong teeth. For us to be able to absorb calcium we need exposure to vitamin D, unfortunately this is available in very few foods. Our major source of vitamin D is through sun exposure. So after you slip, slop, slap make sure you get some sun, it’s good for your teeth and bones!
