Dental Care During Pregnancy in Lagos: What Every Nigerian Mum Needs to Know

Many pregnant women in Lagos avoid the dentist out of fear of harming their baby. This is completely understandable — but in most cases, skipping dental care during pregnancy is actually MORE harmful than going. Dental care during pregnancy in Lagos is safe, important, and sometimes urgent. This guide tells you everything you need to know.

Why Pregnancy Affects Your Teeth and Gums

Pregnancy causes significant hormonal changes — particularly increases in oestrogen and progesterone — that directly affect your gums and teeth. Here is what happens:

Pregnancy Gingivitis

Up to 70% of pregnant women develop pregnancy gingivitis — inflamed, swollen, bleeding gums. The hormonal changes make gum tissue more sensitive to plaque bacteria, causing an exaggerated inflammatory response. You may notice your gums bleeding when you brush or eat, even if you have never had gum problems before. This is very common.

Pregnancy gingivitis typically peaks in the second trimester and resolves after delivery — but only if it’s treated. Ignored, it can progress to periodontitis (serious gum disease), which research links to preterm birth and low birth weight babies. Learn more about gum disease treatment in Lagos.

Pregnancy Tumours (Pyogenic Granuloma)

These are non-cancerous, raspberry-like growths on the gums that can appear during pregnancy — usually between teeth. They are caused by excess plaque build-up combined with hormonal changes. They bleed easily and can be uncomfortable, but they are benign. They often shrink and disappear after delivery, but large or uncomfortable ones can be removed during pregnancy.

Increased Tooth Decay Risk

Pregnant women in Lagos face increased cavity risk from:

• Morning sickness — stomach acid from vomiting erodes enamel
• Food cravings — especially for sweet and carbohydrate-rich foods
• Less thorough brushing — due to gag reflex, nausea, or fatigue
• Dry mouth — some women experience reduced saliva production

After vomiting, rinse with water or a fluoride mouthwash — do NOT brush immediately, as the acid softens enamel and brushing causes abrasion. Wait 30 minutes before brushing.

Enamel Erosion from Acid Reflux

Acid reflux and heartburn are common in the third trimester as the baby pushes against the stomach. Stomach acid in the mouth erodes enamel over time. Rinsing with water, chewing sugar-free gum (which stimulates saliva), and sleeping with your head elevated can help.

What Dental Treatments Are Safe During Pregnancy?

Here is a clear breakdown of what is safe and what to avoid:

✅ Safe at Any Stage of Pregnancy

• Dental check-ups and examinations — essential and completely safe
• Scaling and polishing (professional cleaning) — particularly important to prevent/treat pregnancy gingivitis. See scaling and polishing in Lagos.
• Dental X-rays in emergencies — with appropriate lead apron shielding, the radiation exposure is minimal. However, we prefer to delay routine X-rays until after delivery when possible.
• Local anaesthetic (lidocaine) — safe during pregnancy. Research consistently shows that lidocaine does not harm the baby when used in appropriate dental doses.

✅ Safe in Second Trimester (Best Time for Treatment)

• Fillings for cavities — untreated cavities can become painful infections. It is safer to treat them. See dental fillings in Lagos.
• Tooth extractions (if necessary) — delayed extractions can lead to dangerous infections. If extraction is needed, the second trimester is the safest time.
• Root canal treatment — if infection is present, root canal treatment is safer than leaving an infected tooth.
• Emergency dental work — always safe to treat, regardless of trimester. A dental abscess is far more dangerous to your baby than any dental treatment.

⚠️ Postpone Until After Delivery

• Elective procedures: teeth whitening, veneers, dental implants, orthodontics (starting new treatment)
• Routine X-rays (non-emergency)
• Nitrous oxide (laughing gas) sedation — avoid in first trimester especially

The Link Between Gum Disease and Pregnancy Complications

This is critical information that many Lagos women are not aware of. Research published in major medical journals has found:

• Women with severe gum disease are 7 times more likely to deliver prematurely
• Gum disease bacteria can enter the bloodstream and reach the uterus, triggering inflammatory responses that can induce early labour
• Preterm babies (before 37 weeks) face serious health risks including breathing problems, developmental delays, and infections
• Treating gum disease during pregnancy has been shown to reduce the risk of preterm birth in multiple studies

This is why we strongly urge every pregnant woman in Lagos to have at least one dental check-up and professional cleaning during their pregnancy. It protects both you and your baby.

Best Dental Practices During Pregnancy in Lagos

Here is what to do every day to protect your dental health during pregnancy:

• Brush twice daily with a soft-bristle toothbrush and fluoride toothpaste. If your gag reflex makes this hard, try a smaller toothbrush head and brush more slowly. Some women find brushing easier in the afternoon rather than morning.
• Floss or use interdental brushes daily — plaque between teeth is a major driver of pregnancy gingivitis.
• Use a fluoride mouthwash — rinse after morning sickness episodes (wait 30 minutes to brush after vomiting).
• Eat calcium-rich foods — your baby’s teeth are developing from week 6. Calcium from your diet protects both their developing teeth and yours. Good sources in Nigeria include crayfish, eja eja (smoked fish), ugba (oil bean seed), dairy, and dark leafy vegetables.
• Reduce sugary drinks and snacks — if cravings strike, choose fruits over sweets and rinse with water after.
• See your dentist at least once during pregnancy — ideally in the second trimester for a check-up and cleaning.

What to Tell Your Dentist When You’re Pregnant

Always inform your dentist that you are pregnant and how many weeks along you are. Also share:

• Any medications you are taking (including prenatal vitamins, iron supplements, blood thinners)
• Any high-risk conditions in your pregnancy (high blood pressure, gestational diabetes, placenta previa)
• Your obstetrician’s contact details in case the dentist needs to consult

At Dovers Dental Clinic in Lekki, we are experienced in providing safe dental care for pregnant women. We always consult with your obstetrician when needed and take every precaution to ensure your comfort and safety.

Frequently Asked Questions

Is it safe to have a dental X-ray during pregnancy?

Emergency dental X-rays are safe during pregnancy when a lead apron is used. The radiation from a dental X-ray is extremely low — less than what you receive during a short flight. However, we avoid routine X-rays during pregnancy as a precaution and only take them when clinically necessary.

My gums bleed when I brush during pregnancy — is that normal?

Yes, this is common and called pregnancy gingivitis. Do NOT stop brushing — the bleeding is caused by inflammation, and brushing (gently) is essential to remove the plaque that’s causing it. Make an appointment for a professional cleaning, which will significantly reduce the inflammation. See our guide on scaling and polishing.

Can I use local anaesthetic at the dentist while pregnant?

Yes. Lidocaine (the most common local anaesthetic in Nigerian dental clinics) is safe during pregnancy. Your dentist may use a slightly lower dose and will avoid formulations with adrenaline (epinephrine) if possible, especially in the first trimester. The discomfort of an untreated dental problem is far more harmful than the local anaesthetic.

When is the best time to visit the dentist during pregnancy?

The second trimester (weeks 14–28) is ideal. The baby’s organs are fully formed and the risk of miscarriage has passed. You are not yet uncomfortable from the size of the third trimester. If you need emergency treatment, go immediately regardless of trimester.

Will pregnancy damage my teeth permanently?

The old saying “a tooth for every baby” is a myth — pregnancy does not directly cause you to lose teeth. However, untreated gum disease and cavities during pregnancy can lead to long-term damage. With proper oral hygiene and dental care, your teeth should be just as healthy after pregnancy as before.
