In short: Don’t neglect your oral health while breastfeeding! Most dental treatments, including local anesthesia and X-rays, are perfectly compatible. Simple steps can prevent cavities for both mother and baby, thus avoiding problems like breastfeeding cavities.
Dental Health of Breastfed Babies: Myths and Realities
Breastfeeding is often unfairly associated with “bottle rot”. However, breast milk has protective properties, and suckling at the breast is different. Milk does not come into direct and prolonged contact with the teeth in the same way. The risk of cavities in breastfed babies is therefore naturally lower than with a bottle of milk or sugary drink left overnight.
Nevertheless, vigilance is required after the eruption of the first teeth. Frequent and prolonged night feedings can create an environment conducive to bacteria if milk stagnates. It is therefore crucial to establish good oral hygiene from an early age to minimize any risk and protect your child’s smile. Brushing before bed is a key step.
Dental Care & Breastfeeding: Compatibility and Precautions
| Type of Care / Medication | Compatibility | Recommendations |
|---|---|---|
| Local Anesthetics | Compatible | Lidocaine, articaine. Their passage into breast milk is minimal and they are rapidly eliminated. No need to interrupt breastfeeding. |
| Dental X-rays | Compatible | Exposure is very localized and does not contaminate breast milk. Wearing a lead apron is a standard precaution. |
| Analgesics (Painkillers) | Variable | Prioritize Paracetamol (Acetaminophen) and Ibuprofen. Avoid aspirin and codeine derivatives (unless under strict medical advice). |
| Antibiotics | Variable | Many are compatible (e.g., Amoxicillin). Always inform your dentist about your breastfeeding status so they can choose an appropriate medication. |
| Routine Care (scaling, fillings) | Compatible | Do not postpone these essential treatments. Treating a cavity prevents the transmission of bacteria responsible for breastfeeding cavities. |
Practical Tips for a Healthy Mouth While Breastfeeding
Maintaining excellent oral hygiene is crucial during breastfeeding to prevent cavities and gingivitis. Adopt a rigorous brushing routine: twice a day for two minutes with a fluoride toothpaste. Don’t forget daily use of dental floss to remove interdental plaque. These simple steps are the foundation for protecting your smile and ensuring good oral health while breastfeeding.

Preventing Cavities in Infants: When and How to Act?
Your baby’s oral hygiene begins from birth, long before their first tooth appears. Gently clean their gums with a damp cloth or a silicone finger brush after feedings. As soon as the first tooth emerges, use a soft toothbrush designed for their age with a tiny smear of fluoride toothpaste. This twice-daily brushing is crucial for preventing cavities in breastfed babies, a risk that should not be overlooked.
Delaying dental care during breastfeeding is a bad idea. Most local anesthetics are perfectly safe and do not require any interruption. A healthy mouth is a gift for both you and your baby.

Mother’s Diet: A Pillar for Dental Health
During breastfeeding, your diet directly impacts your dental health and that of your child. A sufficient intake of calcium and vitamin D is crucial to preserve your enamel and build the baby’s future teeth. At the same time, it is essential to limit sugars. Sugary snacks, common with fatigue, promote acid attacks and the risk of cavities, which can affect the child. A good diet prevents breastfeeding cavities.
Frequently Asked Questions: Dental Care and Breastfeeding
Can I have a wisdom tooth extracted while breastfeeding?
Yes, absolutely. Wisdom tooth extraction is perfectly compatible with breastfeeding. The procedure is performed under local anesthesia, and the products used are considered safe. Just be sure to inform your oral surgeon or dentist that you are breastfeeding so they can prescribe, if necessary, pain relievers and antibiotics compatible with your situation.
Does local anesthesia pass into breast milk?
The amount of local anesthetic (such as lidocaine) that passes into breast milk is minimal and clinically insignificant. These molecules have a very short half-life in the body and are considered safe for the baby. You can therefore breastfeed your child with complete peace of mind immediately after your dental appointment, without any delay.
Do I need to pump and dump my milk after dental care?
No, this is a persistent misconception. For almost all common dental procedures (scaling, cavity treatment, extraction, X-rays), it is absolutely not necessary to pump and dump your milk. This practice is only recommended in very rare situations involving specific medications, which is generally not the case in outpatient dentistry.
What are the risks of cavities for my breastfed baby?
Breast milk alone is not considered cariogenic. However, after the first teeth appear, frequent on-demand nighttime breastfeeding combined with insufficient hygiene can increase the risk. It is crucial to start brushing as soon as the first tooth emerges to prevent infant cavities. Good maternal hygiene also limits the transmission of bacteria.
