When Do Babies Start Teething | A Comprehensive Guide

One of the most exciting milestones in a baby’s life is teething. As tiny teeth begin to push through their gums, babies take another step towards eating solid foods and showing off that adorable toothy smile.

While teething is a natural part of development, it can sometimes be challenging for both babies and parents. Knowing when teething starts, what the symptoms look like, and how to ease your baby’s discomfort can make the process smoother.

In this guide, we’ll walk you through when babies start teething, the common signs, teething order and timeline, and practical tips to care for your baby’s teeth.

When Does Teething Typically Start?

According to the NHS, most babies start teething around 6 months of age. However, every baby is different and it may vary when they start teething. Some may sprout their first tooth as early as 3 months, while others may not have a single tooth until after their first birthday.

By the time your child is around 3 years old, they will usually have a full set of 20 baby teeth.

How To Know Your Baby Is Teething

Teething can be tricky to identify because its signs often overlap with normal baby behaviours. Symptoms usually begin a few days before a tooth emerges and can vary from child to child.

Common baby teething symptoms include:

• Excessive drooling (sometimes causing a mild rash around the chin)
• Swollen, red, or tender gums
• Chewing or gnawing on objects
• Ear Pulling or rubbing their face
• Irritability or fussiness
• Mild temperature below 38°C
• Changes in sleeping or feeding patterns
• Loss of appetite

Important: Teething does not cause serious illness. If your baby has diarrhoea, a high fever, or rash, consult a doctor as these are not teething symptoms.

What Teeth Come In First?

At birth, babies already have 20 teeth hidden under their gums. The first teeth to come through are usually the bottom front teeth (lower central incisors).

Baby Teething Timeline

Every child’s teething journey is unique, but here’s a general timeline for when teeth may appear:

Bottom Gum (Lower Jaw):

• 5–7 months: Bottom central incisors (two middle teeth)
• 10–12 months: Bottom lateral incisors (next to central ones)
• 12–16 months: Bottom first molars (further back)
• 16–20 months: Bottom canines (pointy teeth)
• 20–30 months: Bottom second molars (back teeth)

Top Gum (Upper Jaw):

• 6–8 months: Top central incisors
• 9–11 months: Top lateral incisors
• 12–16 months: Top first molars
• 16–20 months: Top canines
• 20–30 months: Top second molars

By around 2½ to 3 years, most children have their complete set of baby teeth.

How To Soothe A Teething Baby

Watching your baby in discomfort is never easy, but there are safe and effective ways to ease teething pain:

• Teething rings: Give your baby a chilled (not frozen) teething ring for cooling relief.
• Massage their gums: Use a clean finger to gently rub their gums.
• Cold washcloth: Let your baby gnaw on a clean, damp, chilled cloth for comfort.
• Safe teething toys: Soft, chewable toys can distract and soothe your little one.
• Feeding relief: If your baby has started solids, offer chilled fruit purées or plain yogurt (if age-appropriate).
• Pain relief: If discomfort is severe, you can give baby paracetamol or ibuprofen (suitable for their age) but always check with a GP or pharmacist first.

Avoid teething gels containing benzocaine or lidocaine as they are not safe for babies.

Taking Care of Your Baby’s Teeth

Even though baby teeth eventually fall out, they play a key role in speech, chewing, and guiding adult teeth into place. Proper care is essential.

1. Brushing Tips

• According to the NHS, you can start brushing your baby’s teeth as soon as they appear.
• Brush twice a day with a soft baby toothbrush.
• Use only a smear of fluoride toothpaste (1,000 ppm for under 3 years old).
• Brush all sides of the teeth and supervise until your child is around 7 years old.

2. Healthy Eating

• Avoid sugary snacks and drinks which cause tooth decay.
• Don’t let your baby fall asleep with a bottle of milk or juice.
• Offer water and healthy snacks like fruit and vegetables.

3. Dental Check-Ups

• Take your baby to the dentist when their first tooth appears or by their first birthday.
• Regular check-ups help prevent cavities and spot early dental issues.

Final Thoughts

Teething is a natural part of your baby’s growth and development. While every child’s timeline is different, knowing the signs and having strategies to ease discomfort can make the process easier.

With a little patience, lots of cuddles, and good oral care from the start, you’ll help your baby through this stage with a happy smile.
