Can teeth demineralization start from not brushing?

Yes: Not brushing your teeth allows plaque and biofilm to accumulate on the tooth surface which can and will lead to demineralization of the enamel.

Absolutely: Lack of hygiene will allow bacteria to produce acids in combination with your dietary acids and they will damage the enamel and cause demineralization which will lead to decay and need for restorations/fillings.

YES !: Not brushing is the primary cause of demineralization. Brush twice per day, for two minutes at a time, with a soft bristled, small headed toothbrush and a pea sized amount of a Fluoride toothpaste. No excuses!

Try MI Paste: If you already have demineralization, application of mi paste ( with or without fluoride) or renew with novamin, have ben shown to promote re- mineralization. For severe cases, your dentist may make custom upper & lower trays which hold those materials or Fluoride gel on the teeth for longer time periods.
