Dr. Haider, your tea tree treatment is definitely excellent for periodontal disease, mine cleared up inside the one month using 3 x daily, and a continued swilling for a further 5 minutes. I had not been able to put chewing pressure on a back molar for some 3 years, but now have no problem with this. Really miraculous!!!!! I also had a problem next to a bottom back molar with a wisdom tooth that is under the surface that kept getting infected with a pus pocket; no longer a problem, all cleared!!! If someone desires to, can they continue with the tea tree oil regularly for an extended time period more often than say once or twice monthly? Many thanks once again!
