teething that worsens lying down

Overview

Teething is the process of new teeth pushing through a baby's gums. This can make the gums sore, red, and swollen. Some babies seem to feel more discomfort when they are lying down, like at nap time or bedtime. This is normal and not a sign of something dangerous.

Yes. Many parents notice that their baby is fussier at sleep times during teething. It is one of the most common teething concerns that health visitors hear about.

Teething affects babies and toddlers, generally from around 4 months up to 3 years of age, as all 20 baby teeth (also called milk teeth) come through. Some teeth cause more discomfort than others.

Symptoms

Common symptoms

• Sore, swollen, or red gums
• More drooling than usual
• Biting, chewing, or gnawing on fingers, toys, or bibs
• Fussiness, especially when put down to sleep
• Poor sleep or waking more often at night
• Mild raised temperature (under 38°C / 100.4°F)

Symptoms in children

• Crying or fussing more when laid flat
• Rubbing their cheek or pulling on their ear on the same side as the sore gum
• Refusing to lie down for nappy changes or sleep
• Dribbling more, which can cause a mild rash on the chin, neck, or chest
• Waking up during naps or at night more than usual

Causes

Main causes

• A baby tooth moves up through the jawbone and presses against the gum, causing local redness and swelling.
• Lying down increases blood flow to the head, which can make the swollen gum feel more uncomfortable.
• Saliva pools in the back of the throat when lying down, which can cause gagging, drooling, or coughing.
• Lying on a firm surface may press against the cheeks and gums, adding pressure to an already tender spot.

Risk factors

• Being in the teething age range (about 4–30 months)
• Several teeth breaking through at the same time, such as molars
• Sucking or bottle-feeding just before sleep, which can increase pressure in the mouth
• A family pattern of earlier or later teething

When to see a doctor

See a doctor urgently if:

• Fever above 38°C (100.4°F) lasting more than 24 hours
• Ear pain symptoms — tugging at ears, rubbing, or irritability — along with fever
• Signs of dehydration — fewer wet nappies, no tears, dry mouth, or sunken soft spot
• Bleeding from the mouth that doesn't stop with gentle pressure
• Your child seems very unwell, floppy, or difficult to wake

Book a routine appointment if:

• If your child is older than 12 months and no teeth have come through yet
• If you are unsure whether the symptoms are teething or an ear infection
• If the fussiness and sleeplessness are making it hard for you or your family to cope

Diagnosis

A doctor, nurse, or health visitor can usually tell if it is teething by looking at your child's gums and hearing about the symptoms. They will check the gums for redness, swelling, and the visible white tip of a tooth. They will also look for other causes, like an ear infection, if the symptoms seem different from normal teething.

What to expect at your appointment

You will be asked how long the symptoms have lasted, when they happen, and whether they mostly occur when your child is lying down. The healthcare professional will then examine your child's mouth, ears, and maybe the neck. You should get a clear explanation and practical advice for soothing. No special tests are required in typical cases.

Treatment

Treatment is about making your child comfortable while the tooth works its way through the gum. It does not speed up teething, but it can reduce fussiness and improve sleep. A mix of gentle gum care, cool things to chew on, and extra cuddles usually works well.

Self-care at home

• Gently rub your baby's gums with a clean finger or a cool, damp cloth for a minute or two before sleep.
• Offer a clean, chilled (not frozen) teething ring. Always supervise your child to avoid choking.
• Let your child chew on a wet, cold flannel — rinse it after each use.
• Wipe away drool regularly to keep the chin and neck dry and prevent a rash.
• Keep a calm bedtime routine — a story, a cuddle, and a dim room can help them settle.
• Give extra comfort at night when pain wakes them. A few minutes of rocking usually helps.
• If your child is weaned, offer cool, soft foods like plain yogurt or mashed banana.

Medical treatments

If home measures are not enough, speak to a pharmacist or doctor. They may suggest an age-appropriate pain relief product for children — always ask for the correct dose for your child's age and weight. Do not use medicated teething gels or tablets unless a health professional recommends them. Some of these are not suitable for young children and may have side effects. Avoid teething necklaces, amber beads, and any homemade remedies, as they can be a choking or strangulation risk.

When is surgery considered?

Surgery is not needed for teething. In extremely rare cases, a tooth may become trapped or a dental cyst may form, and a dentist could consider a small procedure — but this is very unusual and not part of normal teething.

Living with this condition

Teething can feel like a long phase, but each tooth usually causes only a few days of extra discomfort. Keep a few soothing tools clean and ready — like a teething ring, a cold cloth, and plenty of bibs. At night, keep a dim lamp and a glass of water by your bed, and try to rest when your child naps. Remember that this phase is temporary.

Lifestyle tips

• Keep a regular daily schedule for meals, naps, and bedtime to help your child feel secure.
• Use distraction during the day — playtime and fresh air can take attention away from sore gums.
• Try a slightly earlier bedtime during tough teething nights so your child gets enough rest.
• Praise and comfort your child even when they are fussy — they are going through a difficult time.

Diet and exercise

For babies, continue their usual milk (breast milk or formula). For weaned children, cool, soft foods can feel soothing, such as plain yogurt, mashed banana, or well-cooled porridge. Avoid hard or crunchy foods if the gums are sore. Let your child move and play during the day to tire them out, but avoid exciting activities right before bed.

Mental health and emotional wellbeing

It is normal to feel tired, frustrated, or even helpless when your child is in pain and crying at night. Remember that teething is temporary and not a reflection of your care. If you feel overwhelmed, place your baby in a safe cot and step into another room for a few minutes to breathe.

Prevention

Teething cannot be prevented. It is a natural part of growing up. However, you can reduce how much it affects sleep by starting soothing habits early, such as offering a clean teething ring before a tooth appears, and by keeping your child's mouth and face dry to avoid a rash.

Vaccines

There are no vaccines to prevent teething. Vaccinations are a separate and important part of keeping your child healthy.

Screening programmes

There are no screening tests for teething. Regular dental check-ups should begin around the time your child's first teeth appear or by their first birthday, whichever is sooner.

Complications

Long-term outlook

Teething is a phase that passes. Each tooth brings a few days of extra fussiness, then the gum settles and your child gains a new tooth. Most children have all 20 milk teeth by around 3 years of age. With patience, comfort, and help from your healthcare team, this phase is very manageable.
