consultation with dentist

A proper clinical evaluation and detailed clinical history will be required to assess any secondary factors. Otherwise the most common cause of bad breath are local factors like deposits on the teeth and tongue. Hard deposits called as calculus can cause gum inflammation and can be a reason for bad breath but they cannot be removed by toothbrushing. You will require professional teeth cleaning by a procedure called as scaling. You should increase your water intake as 2 litres is definitely insufficient, and although there is no fixed amount recommended for any age or gender, but roughly 4 to 5 litres of water should be consumed daily. Cleaning of the tongue is definitely recommended but the use of tongue scrapers should be avoided because they do more harm than good. Use only your toothbrush to clean your tongue after every time you brush your teeth. Multi vitamins are good for general Physical health but will not solve the problem of bad breath. Similarly mouthwashes can not remove the plaque and can only neutralize it, so they act as adjuncts to tooth brushing and not as replacement. Instead of over-the-counter mouthwashes, you should prefer mouthwashes containing chlorhexidine gluconate 0.2%. The type of toothpaste does not make a difference and it is the brushing technique which is important for maintaining oral health. You can ask your dentist about the best brushing technique which can be demonstrated to you on a model, or you can search for modified Bass technique on YouTube. Regards.
