FAQ

Questions parents most often ask when using HIKARI.

Q1. From what age can children wear it?

The model is chosen according to dental development. During the mixed-dentition stage (about 7–12 years), starting with the soft SOFT model is usual. For children whose permanent teeth have all come in (about 12 and over), the clinician decides the suitable model. Please follow your clinician’s judgement.

Q2. How long should it be worn each day?

While awake, wear it for 1–2 hours in a row during a quiet activity. At night, keep it in until morning. Don’t push at first — get used to it step by step.

Q3. Can my child talk, drink or eat while wearing it?

No. While wearing it, keep the mouth closed naturally — no talking, drinking or eating. For any of these, take it out first and put it back in afterwards.

Q4. Does it hurt to wear?

A foreign-body feeling at first is normal. In the first week, teeth may feel slightly sore in the morning, and this usually fades after about a week. If the mouth keeps hurting or gets a sore spot, don’t trim it yourself — please see your clinician.

Q5. What if it comes out during the night?

Don’t scold. Practise a little longer before bed the next day. If your child still can’t wear it all night after a week, read “What if my child can’t keep it in?” or see your clinician.

Q6. How long will my child need to wear it?

It depends on the child. Please follow your clinician’s instructions.

Q7. Can my child wear it with a stuffy nose?

If the nose is badly blocked, don’t force it. Ask your clinician or pharmacist about a suitable way to manage it first, and wear the trainer once breathing through the nose is easier.

Q8. Where can I get it?

HIKARI is currently supplied only to partner clinicians. Please ask your doctor or dentist.

Q9. Will my child drool more?

Drooling often increases when starting to wear it. It is a normal reaction while the mouth gets used to the trainer and usually settles as your child adapts. If it doesn’t improve, or your child is very uncomfortable, please see your clinician.
