Like most expecting mothers, I jumped into the world of pregnancy as soon as I learned I was pregnant. I bought prenatal vitamins and followed all dietary guidelines. I also started walking daily. I had apps that reminded me of every developmental milestone, and a whole shelf of baby books. There was one area I neglected that was crucial to my health: my oral health.
Who knew that pregnancy could cause such damage to your teeth? Did you know that gum disease could affect the outcome of your pregnancy?
Now that I look back, I wish someone had told me how important it is to brush, floss, and visit the dentist regularly. This is why I am here for you. Because this is a pregnancy issue that often goes unnoticed.

Why do we overlook oral health in pregnancy? Pregnancy and Dental Health
When you’re focused solely on pregnancy tests, morning nausea, and ultrasounds, it’s easy to forget about your teeth. Your belly is growing, not the molars.
I get it. I was the same. Going to the dentist was something I put off. “I’ll do it after this trimester,” “once I feel better,” “when I have time.”
Was I unaware that pregnancy can trigger or worsen dental problems and, in some cases, cause new ones? These problems can affect not only your teeth, but your entire pregnancy if left unchecked.
How hormones affect your mouth
The hormonal rollercoaster of pregnancy is also a rollercoaster for your gums. Your blood volume will increase during pregnancy, and this will result in increased blood flow towards your gums. This, combined with hormonal changes (especially estrogen and progesterone) can make your gums sensitive to bacteria and plaque.
According to the University of Adelaide, hormonal changes may lead to pregnant gingivitis, which is an inflammation of the gums. This condition is often characterised by swollen or tender gums, as well as bleeding. Untreated, it may progress to Periodontal Disease. This is a serious infection of the gums that can cause tooth loss.
Better Health Victoria states that periodontal disease may cause up to 18 premature births in 100. Your gum health could affect whether your baby is delivered too early.
My Wake-Up: Infections, IVF and a Painful Experience
This is a story that I would rather not share, but believe it’s very important.
IVF failed last year. It was emotionally one of the hardest experiences I’ve ever had. It was made worse by the physical pain that I experienced during the procedure. My gums became inflamed and swollen due to the hormone medication. They eventually became infected. My four wisdom teeth all became problematic at the same time. I had to undergo two back-to-back antibiotic courses and have all four of my wisdom teeth surgically removed.
After a long and heartfelt discussion with my fertility specialist, I realised something shocking: that my untreated dental problems may have decreased my chances of having a successful IVF cycle.
My gums could have been the reason why my cycle failed, not because of bad fortune or biology.
I took a short break to address the dental issues and returned stronger. Now I am just a few weeks away from my baby’s arrival. I cannot help but wonder: what if I’d gone to the dentist first? Could I have saved myself the pain, delay and emotional heartache if I had visited the dentist before starting IVF?
If you are currently undergoing IVF, do not wait. Schedule a dental check-up today. You may be able to thank yourself in the future.
Morning Sickness: Its Effect on Teeth
Morning sickness is a common topic of conversation. People talk about how difficult it can be to eat, how it takes away your joy and how ginger becomes a new friend. What you may not know is that nausea during pregnancy can damage your teeth.
Acids from your stomach can destroy the enamel of your teeth. They are more susceptible to damage, decay and sensitivity.

Mater-Mothers’ Hospital warns against brushing your teeth immediately after vomiting, as the acid will soften it and make it more likely to wear off. They recommend rinsing out your mouth with fluoride mouthwash or using water to rinse your teeth. You should wait at least thirty minutes before brushing.
I did not know this in my first trimester, and made the mistake of brushing after each bout of morning sickness. After being sick, it felt right to “clean up”, but this only made the situation worse. What caused the sensitivity that I developed later during pregnancy? It is probably avoidable.
You can’t brush without gagging? You are not alone.
The first trimester of pregnancy was an eye-opener for someone who cannot start or finish her day without brushing their teeth. Every time I tried brushing my teeth, I would gag violently. This was especially true at night, when I felt already tired and queasy. The “furry” mouth feeling was driving me insane, but I couldn’t stop vomiting.
It was tempting to skip brushing. It was tempting to skip brushing, but I knew it could worsen my dental issues and possibly impact my baby’s oral health.
I was able to overcome my struggles with the help of Better Health.
- Use an infant-sized toothbrush.
- Use slow, gentle strokes rather than quick, aggressive ones.
- Close your eyes and concentrate on breathing deeply and evenly.
- Distract yourself by listening to music, podcasts, or affirmations.
- Try different flavours of toothpaste, or brush with water and then fluoride mouthwash.
These small hacks have made a huge difference. It was still painful, but brushing became more manageable and ultimately worthwhile.
Constant Snacking and Tooth Decay
If you’re anything like me, your pregnancy cravings are non-negotiable–especially in the first trimester when food aversions and nausea rule the day.
To me, eating helped to stave off nausea. I became a frequent snacker. I also reached for carb-heavy or sweet snacks, like crackers, fruit gums or sour candies. Combining frequent snacking with hormonal fluctuations and vomiting on occasion, the perfect storm of tooth decay was created.
Every time we eat sugary or starchy food, our teeth can be exposed to acid attacks lasting up to 30 minutes. Our teeth are rarely given a rest due to constant grazing.
It was important to brush regularly, even if you felt nauseated. If brushing was not possible, I chewed sugar-free gum and rinsed with water to reduce the acid buildup.
When should you visit the dentist?
Honestly? As quickly as possible.
The best time to see the dentist if you are trying to get pregnant, receiving fertility treatment or have already become pregnant is right now. Here’s why:
- Before pregnancy, you can take care of any underlying problems like cavities, gum diseases, or wisdom teeth issues before hormones worsen everything.
- Routine cleanings and check-ups during pregnancy are recommended and safe. Most dental work, including root canals and fillings, can be performed during the second trimester.
- After Birth: With a newborn and sleep-deprived parents, it’s not easy to get to the dentist. So take care of your smile while you have time.
If you are pregnant, tell your dentist so they can recommend the right treatment or medication for you.

The Postpartum Tooth Reality
Your teeth still need to be taken care of after the birth of your child. In the months after birth, some women may experience an increase in dental sensitivity and gum problems. This is especially true if they are breastfeeding. Let’s be honest, those sleepless nights and missed meals can make it even more difficult to maintain good oral hygiene.
But your long-term dental health matters. Untreated gum and tooth problems can negatively impact your life and cause complications in the future. Keep your mouth healthy to keep your entire self healthy. Your baby also needs this.
Last Thoughts – Don’t wait until it hurts
During pregnancy, dental care is essential. The effects of gum disease and tooth decay go beyond your smile. They can also affect your pregnancy outcome and fertility journey.
Please let me tell you my story. Do not wait until you are in pain or something goes wrong. Schedule an appointment. Pick up the floss. Consistency and gentleness are key.
Your mouth is no exception. You’re growing life and deserve to feel strong, supported and healthy.
