Teething is more than just sore gums and dribble...

If your baby is suddenly more unsettled than usual, dribbling like a tap, and refusing their usual feeds, teething might be the culprit — but what’s really going on beneath those rosy cheeks?

Many parents don’t realise that saliva actually changes in composition when a baby is cutting teeth, becoming more acidic during this stage. This shift can affect everything from their mood to their skin, sleep and even their appetite.

Let’s break down what happens — and how you can help.

🧪 What Happens to Saliva During Teething?

When babies begin teething, their bodies produce more saliva to help soothe inflamed gums. But it’s not just the amountof saliva that changes — the pH level can drop, making it more acidic than usual.

This change is believed to be the body’s natural response to gum inflammation and the eruption of teeth. However, that extra acidity can come with some unwanted side effects.

🔎 Why Acidic Saliva Can Be a Problem

1. Skin Irritation & Rashes
   Acidic drool can cause irritation around the mouth, chin and neck — often leading to red, bumpy drool rash. It can even extend to the chest and shoulders if bibs or clothing become damp and stay wet (read on to discover our waterproof solution).

2. Sore Bottoms
   Swallowed saliva eventually passes through their digestive system — and that acidity can lead to nappy rash, especially during peak teething days.

3. Upset Tummies
   Some babies experience looser stools during teething. While this isn't due to infection, it’s likely linked to increased saliva swallowing and digestive disruption caused by acidity.

4. Fussiness & Sleep Disruption
   The discomfort caused by sore gums, acidic rash, and unsettled tummies can lead to interrupted naps, night waking, and general crankiness.

👶 Signs Your Baby’s Saliva Might Be Affecting Their Health

• Persistent drooling (especially soaking through bibs/clothes)

• Red, rashy chin or neck

• Refusing bottles or breastfeeds

• Runny nappies without other signs of illness

• Increased crying, clinginess or waking at night

• Nappy rash that appears without diet change or illness

💛 How to Support Your Baby Through Acidic Teething Saliva

1. Keep Skin Dry and Protected

   • Use soft, absorbent bibs like Bibbilyboo's award-winning bamboo dribble bibs with a waterproof backing (gentle on skin, quick-drying, anti-dribble rash shape)

   • Apply a thin layer of barrier cream around the chin and neck if your baby already has a rash before finding our bibs (it will clear within a few days when you switch to our anti-dribble rash shape)

   • Gently pat skin dry instead of wiping to avoid further irritation

2. Offer Soothing Teethers

   • Cold silicone or rubber teethers can help soothe sore gums and reduce inflammation (never freeze teethers as this can cause freezer burn on delicate skin)

   • Rotate a few clean ones through the fridge for extra relief

3. Monitor Nappy Changes

   • Use a protective cream at each change, especially if stools become looser

   • Choose breathable, chemical-free nappies during teething phases

4. Extra Comfort & Cuddles

   • Sometimes, the best remedy is reassurance. Extra cuddles, contact naps, and skin-to-skin time can work wonders.

When to Seek Medical Advice

Teething doesn’t cause fever, vomiting, or severe diarrhoea — so if your baby develops high fever, persistent vomiting, or blood in stools, contact your GP. These symptoms may indicate something else beyond teething.

Final Thoughts

Teething can be a tough phase for both babies and parents — but understanding what’s going on behind the scenes (like saliva acidity) can make a world of difference. With the right care, a few essentials, and lots of love, you can help your baby through it with comfort and confidence.
