Pregnancy causes hormonal, dietary and physical changes that directly increase the risk of gum disease, tooth decay and enamel erosion. Elevated progesterone and oestrogen levels make gum tissue more reactive to bacteria, while increased calorie intake and morning sickness expose teeth to more sugar and acid than usual.
At Pure Smiles in Fulham, we advise pregnant patients and those planning to conceive to prioritise dental care before, during and after pregnancy. Understanding the oral health changes that occur during pregnancy is the first step towards protecting your teeth and your baby’s health. learn more
Pregnancy gingivitis affects up to 75% of pregnant women. It is caused by hormonal changes that increase blood flow to the gums and heighten the body’s inflammatory response to plaque bacteria.
| Pregnancy Gingivitis Sign | What It Looks Like |
|---|---|
| Red, swollen gums | Gum tissue appears puffy and darker in colour |
| Bleeding when brushing or flossing | Blood on your toothbrush or in the sink |
| Tender gums | Discomfort or sensitivity along the gum line |
| Bad breath | Bacterial build-up from inflamed gum tissue |
Pregnancy gingivitis is not inevitable. It is a treatable and largely preventable condition. Maintaining thorough oral hygiene and attending regular dental appointments during pregnancy significantly reduces the risk.
Pregnancy increases the risk of tooth decay through several pathways:
Research has shown that bacteria from untreated gum disease can enter the bloodstream and potentially affect pregnancy outcomes. Maintaining good oral health during pregnancy is not only about protecting your own teeth. It is also about reducing potential risks to your baby’s development.
| After Vomiting | Why It Matters |
|---|---|
| Rinse with water or a fluoride mouthwash immediately | Neutralises stomach acid on tooth surfaces |
| Do not brush for at least 30 minutes | Acid-softened enamel is vulnerable to abrasion from brushing |
| Chew sugar-free gum if possible | Stimulates saliva production to help neutralise acid |
Certain foods and drinks should be adjusted during pregnancy both for general health and for oral health:
| Food or Drink | Pregnancy Dental Guidance |
|---|---|
| Sugary snacks and drinks | Limit frequency; choose tooth-friendly alternatives |
| Acidic fruit and juices | Consume in moderation; rinse with water afterwards |
| Caffeine | Reduce intake; caffeinated drinks are also acidic |
| Alcohol | Avoid entirely during pregnancy |
| Calcium-rich foods (cheese, yoghurt, milk) | Increase intake to support both your teeth and your baby’s developing bones and teeth |
Pregnant patients should attend dental appointments more frequently than usual. Pure Smiles recommends check-ups every three to six months during pregnancy so that:
Always inform your dentist that you are pregnant at every appointment so that appropriate precautions can be taken regarding X-rays, medications and treatment planning.
| Treatment | Safety During Pregnancy |
|---|---|
| Routine check-ups and cleaning | Safe throughout pregnancy; recommended more frequently |
| Fillings for active decay | Safe; best performed in the second trimester |
| Emergency dental treatment | Safe and important to address promptly at any stage |
| Elective cosmetic procedures | Best deferred until after birth |
| Dental X-rays | Avoided unless clinically essential; modern X-rays use very low radiation with appropriate shielding |
The second trimester (weeks 14 to 26) is generally considered the most comfortable time for dental treatment, as morning sickness has typically subsided and the later-stage physical discomfort of the third trimester has not yet begun.
If you are planning to conceive, booking a comprehensive dental check-up before pregnancy is highly recommended. This allows your dentist to:

Yes. Dental check-ups and professional cleaning are safe throughout pregnancy and are actively recommended. In fact, skipping dental visits during pregnancy increases the risk of gum disease and tooth decay progressing undetected. Always inform your dentist that you are pregnant.
Pregnancy itself does not cause teeth to fall out, but untreated pregnancy gingivitis can progress to periodontitis, which damages the bone supporting your teeth. This is preventable with good oral hygiene and regular dental care during pregnancy.
Continue using your regular fluoride toothpaste during pregnancy. Fluoride is safe and essential for protecting your enamel. If the taste or smell of your usual toothpaste triggers nausea, try a milder flavour or use a fluoride mouthwash when brushing is difficult.
Your child’s first dental visit should occur within six months of their first tooth appearing, or by their first birthday, whichever comes first. Early dental visits establish good habits and allow the dentist to monitor tooth development from the start. learn more
