Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern.... As per your query flossing helps in removing micro deposits from the areas in between the two teeth and a proper flossing technique helps in preventing cavities over the surface in between the two teeth and as the cavities in on the walls where it contact the adjacent tooth remains hidden at times which can lead to deep infection by the time it is noticed.. -You can use a waxed floss which slips easily in between the two teeth and should floss in the direction away from the gums to prevent deposits to get impacted in gums and cause infection.. -Mouthwashes help in keeping microbial count low and hence they help in preventing oral and dental infections.. -Nutritions play an important role as in case of deficiency of nutrients like Vitamins,iron etc can lead to several gum and mouth problems like mouth ulcers,inflammation of mucous membranes and gum swellings.. -To prevent gum and tooth infection take more of raw fruits and vegetables,drink plenty of water,avoid sticky and sweet foods and always gargle after eating.. -Consult a dentist every 6 months for a regular dental checkup tp prevent any oral infection from progressing.. Hope this information helps.. If you find the answer helpful please give me a Five Star Review and click on found the answer helpful as a token of appreciation.. Thanks and regards..
