The front teeth are connected to bladder and kidneys by energetic meridians so I would strongly suspected that dead tooth with the root canal is interfering the energy flow on that particular meridian. If there's is an infection on that tooth, ozone therapy might be able to temporarily resolve it but youll still have a dead tooth in that meridian so your bladder problems can still persist. It certainly is your decision wether or not your should have it removed (tougher decision when dealing with front teeth because of aesthetics). I have had 2 extractions done not 3 weeks ago (molars) and I'm looking to get bridges when I can afford it but it takes 3 months for the extracted site to fully heal so that a bridge can be placed.
