Dentistry/dental work and child hypothyroidism


m.y daughter who will be turning 6 was born with hypothyroidism .the first two years her t4 and TSH levels were up and down we change medication from levothyroxine to synthtoid. she has been stable so far  these past few years. However, her last letter results which were two weeks ago were at a 9.68 which is higher than normal. she is scheduled work in 2 months for dental work and needs local anesthetic but is not scheduled to have a thyroid blood drawn until 3 months .should I wait until I get the results from the blood before I go through with the dental treatment

Hi Nichol,

This question is really out of my expertise.  I did not even know what hypothyroidism is.  So after looking up on Google I found the following definition of Hypothyroidism:  "....a condition in which your thyroid gland doesn't produce enough of certain important hormones."  That's about the extent of it for me.  The article said that this condition is usually more common in adults over 60.

So my layman's guess would be to wait until the latest blood work results are complete before doing any dental treatment.  Most dental work is not life threatening.  However, to make a mistake on a child with Hypothyroidism may have unexpected consequences.

Just one more thing.  Even though most dentists have the surname of "Doctor" they are not necessarily an MD, or "Medical Doctor."  I would talk this out with your own pediatrician or even a endocrinologist.  Make sure they are aware of the latest blood work.

Best Regards,

My area of expertise from the patients point of view would be Dentistry/TMJ plus the speech challenges that these jaw and bite problems sometimes represent. Over the years I have seen a multitude of dentists, orthodontists, oral surgeons, speech therapists, neurologists and other health professionals who all had an opinion about my TMJ/bite problem. I AM NOT A DOCTOR...but would purely be a patients point of view type person. I "get it" when people say they tried to explain to their dentist what their TMJ/bite problem is and that they are misunderstood. I can listen to people's trials and tribulations and there is a good chance I have been down that road before. I can make suggestions as to what people can do at home, or what questions to ask their doctor or dentist when they visit. I will try and recall information or experiences that may be helpful to you.


About 25 years ago, I had my wisdom teeth out and since then my bite has never felt "normal." For whatever reason, the first sensation I remember was not that my bite was off.....but rather that my normal tongue and speech patterns had been impeded. I spent years going to different dentists, who lumped me into their generic version of what they knew about TMJ. The majority of dentists believe they can treat TMJ, but only those whose primary focus is TMJ treatment, are really any good at it. Any dentist, can take an impression of your teeth, send that impression off to the lab and have them make a night guard. That is the easy part. The tricky part is what the dentist does with the night guard, once receiving it from the lab. The dentist has to do a "fitting" where they tailor the night guard to be evenly balanced and comfortable in your mouth. Sometimes it can take a few visits, because further adjustments need to be made to the night guard appliance, to get it just right. I have found that dentists, who have had the most practice, do a better job at fitting your appliance. It's almost like an art form.
