Tartar is smelly and should be treated as soon as possible, mainly through scaling to remove calculus and plaque from around the teeth. Normally, you must pay attention to good brushing, and learn to use dental floss to clean the gaps between the teeth, so that you can reduce bad breath. If timely treatment is not carried out, tartar and plaque on the teeth will stimulate inflammation of the gums and produce periodontal disease, which will further aggravate the situation, and there will be noticeable bad breath, and later on, it may also lead to loosening of the teeth. Therefore, after finding tartar on the teeth, which is difficult to remove by brushing, you should go to the hospital as soon as possible for treatment, through scaling or instruments to remove the calculus cleanly, and then maintain good oral hygiene will be able to effectively reduce the symptoms.
