Don't think so. I've dived with people with braces before.

Wearing 3mm wetsuit. Long sleeve with short pant. Last time everytime i dive I get shivering. But this time a lot better after with wetsuit. Going to toilet also easy and convenience with separate top and btm. Everything is good so far. Enjoying around with fishy. Small Shrimp climb walk on my hand.
I think For me, everything is easy and convenience is the best. Underwater-Up down left right upturn down turn, surface-easy release and attach, bring dive gear up/down to boat. Really happy dive today. Because mostly all equipments I newly purchase suit me well.

How to be more careful? decrease the ascend / descend speed? or deepstop? hmm.gif

Equalize as much as possible. If pain, stop and try again. If still pain, abort dive.

For those curious about why our diving syllabus teaches the equalizing techniques the way they do, here's my attempt to simplify it:

First, notice the anatomy of our Eustachian tube..The opening, found at the back of the throat, is cone-shaped and is shut most of the time.

When you pinch your nose and blow hard, you create a high pressure area at the throat which forces air past the shut opening. I think everyone knows this by now.

However, if you equalize only when you feel the pressure/pain, the air within the eustachian tube has already been compressed, pulling the soft structures, especially the walls of the tube and the opening, closer and tighter together. This makes it harder to equalize.

If you keep going down despite failing to equalize, the excess negative pressure may:
-pull fluid from the walls of the tube, causing the tube to fill up with fluid, looking like an infection as i mentioned previously (aka barotitis media),
-suck in the soft membranes (eardrum, round/oval window) so hard it ruptures them

Hence the recommendations are to:
-equalize regularly in anticipation, even before you feel the pressure
-stop descending and attempt to equalize if you fail,
-ascend slightly and attempt again if you still fail

Most of the time these steps will work, unless you have an underlying problem. Which is the sniffles and a blocked nose in most cases. An infection swells up the walls of the tube, throat and opening, making it very hard to open them up. And that is why decongestants such as Clarinase may help.

The reverse squeeze is less common since air escapes easier from the inside. Unless of course your tube and opening walls are swollen as above. The eustachian tube opening has a few muscles surrounding it, which contracts and opens up the tube when you swallow.

Sometimes, even if you do not have a nose block or have taken some decongestants, you may find that equalizing is a hit-miss thing. Sometimes easy, sometimes impossible, on the same dive. This may be due to mucus blocking the opening of the tube. I find that swallowing a few times before equalizing again helps sometimes, but not always.

Hope this helps. Feedback and corrections are much appreciated.
