Dummies (also known as pacifiers or soothers) can be incredibly helpful during infancy to assist with soothing unsettled babies, aiding sleep, and offering comfort during teething. But as your child grows, you might wonder: Are dummies bad for teeth? At what point do they become harmful instead of helpful?
We’ll explain the pros and cons of dummy use from a dental perspective, when issues may arise, and how to protect your child’s smile while using dummies responsibly.
What Are the Benefits of Using Dummies?
Dummies aren’t all bad, in fact, they offer some important short-term advantages when used appropriately during infancy.
Comfort and Soothing for Babies
Sucking is a natural reflex for babies. Dummies provide a calming effect that can help soothe fussiness, improve sleep routines, and provide emotional comfort—especially in new or overwhelming situations.
Link Between Dummies and Reduced SIDS Risk
According to Red Nose Australia—the leading authority on safe infant sleep in Australia—there is strong evidence that dummies are associated with a reduced risk of sudden infant death (SIDS) when used consistently at sleep times. That said, dummies should never be forced if a baby resists.
Temporary Aid for Teething or Minor Pain
Some research suggests that pacifiers can offer short-term relief during teething or discomfort during minor procedures like immunisations.
Easier to Stop Than Thumb Sucking
Unlike thumb sucking—which is harder to control—dummies can be taken away when the time is right. This gives parents more influence over when and how to end the habit.
When Can Dummies Start to Affect Teeth?
While dummies offer clear early benefits, prolonged use can impact oral development as your child grows.
Dental Changes with Ongoing Dummy Use
Extended dummy use—especially beyond 18 months—can interfere with the development of the teeth and jaws. Dental issues associated with prolonged pacifier use include:
- Anterior open bite – where front teeth don’t touch when the mouth is closed
- Posterior crossbite – where back teeth don’t align properly
- Overjet – protrusion of the upper front teeth
These issues can also increase the risk of mouth breathing, speech delay, and sleep disorders.
What Age Should Dummy Use Stop?
Dummy use should ideally begin to taper off around 18 months, with complete weaning by 3 years of age (36 months). The longer a child continues using a pacifier past this age, the higher the risk of long-term dental and developmental concerns.
Tips for Reducing Dummy-Related Dental Risks
If your child uses a dummy, there are steps you can take to minimise any potential impact on their dental health.
Healthy Dummy Habits
- Choose an orthodontic dummy with a soft, flatter teat to reduce pressure on growing teeth.
- Look for a one-piece design with a firm plastic shield to lower choking risk.
- Only use dummies that can be boiled or sterilised to keep them hygienic.
- Never dip dummies in honey or sweet substances, as this can lead to tooth decay and oral infections.
How to Wean Off Dummies
- Gradually limit use during the day—offer other comfort techniques such as holding, rocking, swaddling, or singing.
- Reserve dummy use for specific times or places, such as naps or car rides, to help your child adapt slowly.
- Start reducing dummy use overnight by re-settling your child without it when possible.
- If your child is old enough, have a gentle conversation about stopping. Use positive reinforcement (like a reward chart or special treat) rather than criticism or punishment.
Alternatives for Soothing
Try replacing the dummy with:
- A comfort toy or soft blanket
- White noise or lullabies at bedtime
- A teething ring (for babies experiencing discomfort)
When to See a Dentist About Dummy Use
Even with the best intentions, it can be hard to tell if dummy use is causing problems. That’s why early dental check-ups are so important.
Signs Your Child May Be Affected
- Front teeth that appear misaligned or pushed outward
- Difficulty bringing upper and lower teeth together
- Signs of mouth breathing or speech delay
- Trouble chewing or biting properly
Importance of Early Dental Visits
At No Gaps Dental, we recommend a child’s first dental visit by their first birthday, or within six months of their first tooth. These early visits allow your dentist to monitor development and detect any dummy-related issues before they progress.
