Does thermal imaging effective at pinpointing cavitations?

I was told by a Lyme expert (I have Lyme) that the first thing I need to do is see a biological dentist to see if I have any cavitations that are causing infections. She also mentioned getting thermal imaging done. I can't find any biological dentists here in this part of Virginia that have cavitats - but there is a medical facility that does thermal imaging. I guess I am wondering if any of you think that thermal imaging would be able to detect cavitations - even minor ones. Thanks! PS - I have had years of chronic sinus infections/allergies so she may be on to something.
