Like i told you,infection can be cured but the source(tooth),still remains.a tooth has three major parts:enamel,dentine and pulp present in that particular order from outer surface towards inner.when a tooth is cut,like in your case,for capping,the dentine part gets exposed which contains offshoots from pulp called dentinal tubules.enamel doesn't have any blood supply,so bacterias accumulating on it(plaque) are not transmitted to the inner parts of the tooth.some breach in enamel can lead to exposure of dentine,which transmits bacterias into the pulp through dentinal tubules.this breach may occur bcos of various reasons like cavity,attrition of teeth,abrasion of teeth,tooth fracture etc.in your case the cause was the cutting of tooth for capping.now in most of the cases no problem occurs after capping as cap is put usually between 1-3 days after cutting(bacterial invasion through dentine takes weeks to months).rarely though problems are seen in the capped tooth which can't be predicted beforehand.so in these cases cap is removed and root canal of the tooth is done after which same or different cap is again put on the tooth.now even though you're free from symptoms,the source of the problem,the infected tooth still remains.till that is not treated you may face problems in future.the alternative therapy cannot correct the damage that has your tooth already suffered.(written via mobile)
