Hi Aisha, It is very important to tell your dentist about certain things in regard to dialysis. Most definitely mention your low calcium levels. The side effects of calcium imbalances on your bones are similar to what happens with your teeth. This is something a dentist would want to know if they care about the overall long term oral health of their patients.Another important point to mention while at a dental appointment is the use of heparin or whatever blood thinners you take/use for treatment. When they go poking around your mouth, especially going near your gum line and doing that awful scaling, you will bleed more easily than other patients. Even if they've taken a recent medication list from you, it's always good to reiterate this point.And since dialysis patients can be more prone to infections, any poking around the mouth can be an opportunity for infection. Some suggest taking an antibiotic prior to all dental appointments. I’ve been advised, even post transplant, to take an antibiotic only if the dentist is going to do something “dirty”, such as pulling a tooth or root canal. Talk to your neph about this first and they'd know better about your particular case.One other point is that dialysis patients typically have dry mouth due to fluid restrictions. That has a negative effect on oral health. More apt to develop gum disease, tooth decay and just general nasty mouth feeling.I have a huge case of dentophobia but still go for check-ups/cleanings 3 or 4 times a year. The dental clinic offers nitrous oxide to their “jumpy” patients so I took on the extra fee for that. The first time I didn’t mind it, it got me through a filling, but the second time? Feeling numb scared the heck out of me so I never used it again. Now it’s a case of mind over matter and I’m more at ease with the whole process. I tell myself that it's for my own good and I want to keep my "natural teeth" going as long as possible.This could just be "weird me problems" but if the dental chair was positioned too flat, my catheter would jump/thump/have a spasm. It occurred more than once during the appointment and it happened at every appointment so it wasn't a "one off" thing. Anyhoo, I'd advise the hygienist to adjust the chair to a point that part didn't feel so "heavy." I dunno, I'm just weird. But the point is, if you are uncomfortable, definitely say something.Now, my only complaint about going to the dentist occurs when the male hygienists don’t wear deodorant and their armpits hover above my head. What a trapped feeling! Good luck and I hope you make it to the dentist soon. Dental discomfort is definitely a “hopeless” feeling sometimes.
