Why retainers are important

I had a patient come in this afternoon for an appointment that was marked in the diary as “retainer review”.

When I opened up his notes, it turned out that his orthodontic treatment finished over 3 years ago and we hadn’t seen him in almost 3 years. At that stage we had made him a spare retainer and he never came back to us to have it fitted.

When he came in, I said “so we haven’t seen you in nearly 3 years.”

“Yeah, I know. Sorry about that. Really busy with the leaving cert and that sort of thing,” he said. He explained that his retainer was worn and cracked now and he needed a new one.

I asked if he’d worn his original retainer that we gave him back in 2022, and he said he had, and when I looked at his teeth they seemed pretty straight, so I took a chance and we dug out the 2022 spare retainers and I pushed them on to the teeth.

They slipped on to the teeth without effort.

Top and bottom retainers.

Fitting exactly.

I was very surprised, as plenty of people tell you they’re wearing their retainers but the truth might be a little bit at odds with that.

Or a lot.

This guy was in the age group for a high chance of crowding in the lower front teeth after orthodontic treatment.But he wore his retainers and got the benefit of that – no need to wait for us to make him a new retainer, he walked out with his teeth under the control of a retainer that was made for him 3 years ago and sat in a cupboard waiting for its chance to serve.

I gave him his “discharge instructions” and, 3 years later than expected, he finally completed his last review appointment and returned to the continuing care of his own dentist.

Didn't know she didn't smile

Had a young patient in for the first time last week, accompanied by her mum. They both knew what needed fixed - a top tooth biting inside the lower teeth instead of outside them: a crossbite.

I went through my usual orthodontic assessment for a new patient, measuring this and that, but I also asked “would your teeth stop you smiling for a photo?”

“Yes.”

I could see her mum’s face change tone, and she said “you never said that, you never told me you didn’t smile.”

At the end of the appointment, after she’d left the room her mum said the same thing to …

I'd like to cancel my son's appointment

It was something like a scene from Derry Girls or The Inbetweeners, but last week we actually had a teenage patient phone the practice pretending to be his own father to cancel the appointment he was meant to attend that day.
