How long do I need to wear my retainer for?

Many, many years ago, orthodontist typically would say you only need to wear your retainers for 2 years; or until you turn 18 years old, if you had orthodontic treatment as a child. READ MORE
Many, many years ago, orthodontist typically would say you only need to wear your retainers for 2 years; or until you turn 18 years old, if you had orthodontic treatment as a child. However, teeth will always shift throughout your lifetime whether or not you had orthodontic treatment. Therefore, I tell my patients that they need to wear their retainers full-time for 6 months then at night . . . forever. Best regards, Dr. Glenn Frial

My daughter is 4 years old and is used to sucking her thumb. Will it cause her teeth to grow outwards?

Yes, prolonged thumb sucking can cause the upper teeth to protrude. It can also create an open bite where the front teeth don't touch among other things. Most children stop between READ MORE
Yes, prolonged thumb sucking can cause the upper teeth to protrude. It can also create an open bite where the front teeth don't touch among other things. Most children stop between the ages of 2 and 4. Positive reinforcement is usually the best way to help them stop. For example, instead of getting angry when they suck their thumb, praise them when they are not. Your dentist can encourage your child to stop and give some tips like putting a band-aid on the thumb as a reminder. As a child gets older and they continue, consult with an orthodontist as a habit appliance may be needed.

The American Association of Orthodontists recommends that all children be screened by an orthodontist by age 7. We can spot early jaw growth problems as well teeth issue at an early age. In some circumstances, early intervention treatment may be needed, which is what we call Phase One treatment. In other cases, treatment may not be needed at this time, but seeing an orthodontist will give you peace of mind. Hope this helps, Dr. Frial

How long does it take for teeth to set with retainers?

It normally takes a minimum of 6 months for the teeth and bone to stabilize. It can sometimes take longer, especially for adults. Therefore, my retainer protocol is to wear a retainer full-time for a minimum of 6 months after braces are removed. After 6 months, if the teeth have stabilized, then night time wear is prescribed forever. Teeth will always move throughout life, even if you have never worn braces. There are many things that can cause teeth to move (e.g., tongue thrust, playing an instrument like a flute, chewing more on one side, etc.). Therefore, the only way to keep your teeth straight is to wear your retainers at night forever. That is exactly what I do.

Hope this helps,

Dr. Frial

My son is 8 years and his permanent teeth are crooked. Is it too early to go to an orthodontist?

The American Association of Orthodontists recommends that all children be screened by an orthodontist by age 7. The dentist who saw him may be right, but an orthodontist can spot jaw growth or teeth eruption problems at an early age. Sometimes patients can benefit from early intervention as we can guide the growth of the jaws to help permanent teeth come in properly. Also early intervention can prevent more extensive treatment later in life that may require pulling of permanent teeth or even jaw surgery.

I wear my retainer, so why are my teeth still shifting?

If you feel your teeth are moving, you should see your orthodontist. He may just need to tighten your retainer. You may also need to wear them more than at night or change the retainer type. Different orthodontists have different protocols for retainer wear. My retainer protocol is to wear a retainer full-time for a minimum of 6 months after braces are removed to allow the bone and teeth to stabilize. I don’t go straight to night time wear after braces removal because the teeth are still unstable. After 6 months, if the teeth have stabilized, then night time wear is prescribed.

What if only one tooth is crooked?

Not necessarily. A retainer may be all that is needed. Clear Aligner therapy like Invisalign ® or ClearCorrect ® is another option. Braces will also correct the single tooth and READ MORE
Not necessarily. A retainer may be all that is needed. Clear Aligner therapy like Invisalign ® or ClearCorrect ® is another option. Braces will also correct the single tooth and yes, it will move your other teeth, but that may be necessary. Many times, what you see as a single tooth may actually be more than like. For example, a patient will tell me that have one lower tooth that goes inward. However, upon my exam there is more going on. The upper tooth directly above the lower tooth is also going inward and if we don’t move it forward, we will not be able to move the lower tooth forward. The best thing to do is to get an evaluation to see your options.
