5 Reasons to Replace Missing Teeth (Even Just One)
6 April 2025
A child’s smile undergoes remarkable changes from infancy through adolescence. Each stage of dental development plays a key role in their oral health, speech, nutrition, and self-esteem. Understanding how a child’s teeth grow and evolve over time allows parents and caregivers to support healthy habits and prevent common dental issues. In this blog, we explore how a child’s smile develops—step by step.
The Start of Teething: Baby Teeth (6–12 Months)
Most babies begin teething around six months of age, though this can vary. The first teeth to emerge are usually the lower central incisors, followed by the upper central incisors. By around age three, children typically have a complete set of 20 baby (primary) teeth.
These baby teeth help your child chew, speak, and smile. They also hold space in the jaw for the permanent teeth that will come later. Despite their temporary nature, baby teeth are essential and must be cared for properly.
Care Tips for Baby Teeth:
- Clean your baby’s gums with a soft cloth before the first tooth appears.
- Begin brushing baby teeth with a soft toothbrush and a smear of fluoride toothpaste.
- Book your child’s first dental visit by their first birthday or within six months of their first tooth erupting.
Toddler to Early Childhood: Caring for Primary Teeth (1–5 Years)
As children grow, they become more independent with eating, speaking, and brushing. This period involves continued eruption of baby teeth, usually completed by age three. By now, your child will be using their teeth to chew a wide variety of foods and develop clearer speech.
During these years, children also begin to learn how to brush their own teeth—but they still need supervision to ensure proper technique and thorough cleaning.
What to Monitor:
- Avoid prolonged use of bottles or sippy cups with sweet drinks, which can lead to early decay.
- Discourage thumb sucking or dummy use beyond age three to avoid pressure on developing teeth and jaws.
- Encourage twice-daily brushing with fluoride toothpaste and schedule dental check-ups every six months.
Early School Years: Preparing for Permanent Teeth (6–8 Years)
Around the age of six, children begin to lose their baby teeth. The lower and upper front teeth are usually the first to go. This stage marks the beginning of the mixed dentition phase, where baby and permanent teeth exist side by side.
During this time, the first permanent molars—also called “six-year molars”—emerge at the back of the mouth. These teeth are critical for chewing and establishing the bite. As they don’t replace any baby teeth, they can sometimes go unnoticed.
Why This Stage Matters:
- Newly erupted permanent teeth are more vulnerable to decay due to deeper grooves and pits.
- Good brushing habits are essential, and your dentist may recommend protective sealants.
- It’s important to maintain space and alignment as more permanent teeth come in.
Middle to Late Childhood: More Adult Teeth Emerge (9–12 Years)
By this stage, children lose more of their baby teeth, making way for their permanent canines and premolars. The jaw and facial bones continue to grow, making space for these larger teeth.
This is also a period of increased independence, with children brushing and flossing on their own. However, they may still need reminders or supervision to maintain consistency.
Helpful Habits:
- Reinforce proper brushing and flossing techniques.
- Offer a balanced diet rich in calcium and low in added sugars to support strong teeth.
- Continue regular dental visits to monitor development and maintain oral health.
Teenage Years: Completing the Smile (13–17 Years)
By the early teen years, most children have received their full set of 28 permanent teeth (excluding wisdom teeth). The focus now is on maintaining healthy habits that protect their teeth for life.
Teens are often more exposed to soft drinks, snack foods, and irregular brushing habits—particularly with busy schedules and lifestyle changes. Education and support from parents and dental professionals are key during this time.
Ongoing Care Tips:
- Reinforce the importance of brushing twice a day and flossing daily.
- Encourage the use of a fluoride toothpaste to strengthen enamel.
- Provide guidance on healthy food and drink choices to protect against cavities.
- Ensure dental check-ups continue every six months.
Wisdom Teeth and the Young Adult Transition (Late Teens to Early 20s)
Wisdom teeth, or third molars, usually begin to appear between the ages of 17 and 21. Not everyone develops them, and some may only develop one or two. In many cases, there may not be enough space for these teeth to emerge properly.
Regular dental check-ups, including X-rays, help monitor the development of wisdom teeth and determine whether removal is necessary.
Things to Discuss with Your Dentist:
- Monitoring for signs of impaction, infection, or crowding
- Timing and planning for potential removal
- Managing discomfort if and when wisdom teeth begin to erupt
