Madali masiraan ng ngipin

Any advice? I do like sweets but I regularly brush my teeth thrice a day and also floss. Can't help but notice nagkaroon pa rin ako ng black spot in between two of my teeth but I'm planning to go for a cleaning and if in case, papasta. Nacoconscious na kasi ako kasi recently lang din ako nagpabunot, ayoko na mabunutan uli and maging toothless pagtanda ko so I want to invest im oral health badly 😭
