Quick Answer
Yes. Teething is one of the most common causes of sudden bottle refusal in babies who were previously feeding well. The pressure and suction involved in bottle feeding can aggravate sore, inflamed gums, making feeding uncomfortable or even painful. If your baby has started refusing the bottle and is also showing other signs of teething, the two are very likely connected.
When Does Teething Start?
Teething can begin as early as 3 to 4 months, well before any teeth are visible through the gum line. The first teeth to erupt are typically the lower central incisors, usually appearing between 6 and 10 months, but the process of the tooth moving through the gum tissue begins weeks or even months before eruption. This means your baby can be experiencing teething discomfort long before you can see or feel anything.
Why Teething Causes Bottle Refusal
When a baby sucks on a bottle teat, the suction creates pressure on the gums. During teething, the gum tissue is inflamed and sensitive as the tooth pushes through. This pressure can cause discomfort that makes your baby pull off the bottle, arch their back, or refuse to latch onto the teat at all. The discomfort is often worse at the beginning of a feed when the gums are most sensitive, which is why some teething babies will take a few sucks and then refuse to continue.
Signs That Teething May Be the Cause
- Increased drooling (often the first sign, appearing weeks before a tooth erupts)
- Chewing on hands, fingers, toys, or anything within reach
- Red, swollen, or bulging gum ridges
- Fussiness and irritability, particularly in the late afternoon and evening
- Disrupted sleep
- Pulling at ears (though this can also indicate an ear infection, so worth checking with your pediatrician if persistent)
- Mild temperature elevation (true fever above 38°C is not caused by teething and warrants a call to your pediatrician)
What to Try
- Chill a teething toy before feeds: Offer a chilled (not frozen) teething ring or toy for 5 to 10 minutes before a feed. The cold helps reduce gum inflammation and numbs the area slightly, making feeding more comfortable
- Gently massage the gums: Using a clean finger, gently rub the affected gum area for a minute or two before offering the bottle. The counter-pressure can temporarily relieve discomfort
- Try a different teat shape or flow rate: Some babies find a softer, more flexible teat more comfortable during teething. A teat that requires less suction effort can also reduce gum pressure. The Emulait Classic Bottle features a breast-shaped nipple designed to work with your baby's natural sucking motion, which may be more comfortable for teething babies than a standard cylindrical teat
- Feed more frequently in smaller amounts: If a full feed is too uncomfortable, try offering smaller amounts more frequently to ensure your baby is getting adequate nutrition without prolonged gum pressure
- Offer cooler milk: Some teething babies who normally prefer warm milk will accept slightly cooler milk during a teething episode, as the cooler temperature can soothe inflamed gums
- Ask your pediatrician about pain relief: For significant teething discomfort, your pediatrician may recommend an appropriate infant pain reliever. Always follow professional guidance on dosage and frequency
How Long Does Teething-Related Bottle Refusal Last?
Teething-related bottle refusal typically resolves once the tooth has fully erupted through the gum line and the acute inflammation subsides. This can take anywhere from a few days to a couple of weeks per tooth. Unfortunately, teething is an ongoing process throughout the first two years, so some babies experience repeated episodes of feeding disruption as new teeth come through.
When to Seek Help
Speak to your pediatrician if:
- Your baby is refusing all feeds and showing signs of dehydration (fewer wet nappies, dry mouth, sunken fontanelle)
- Your baby has a true fever above 38°C, which is not caused by teething and may indicate illness
- Bottle refusal persists for more than 2 weeks
- Your baby is not gaining weight appropriately
- You are unsure whether the cause is teething or something else
Key Takeaway
Teething is a very common cause of sudden bottle refusal. The suction and pressure of bottle feeding can aggravate inflamed gums, making feeding uncomfortable. Chilling a teething toy before feeds, gently massaging the gums, trying a softer or differently shaped teat, and offering smaller, more frequent feeds can all help. Teething-related refusal is temporary and resolves once the tooth erupts, though it may recur as new teeth come through.
