Hey Makhai,
Welcome to the forum. So many things here. Nothing is ever black and white. Let me ask you this:
If you were being honest with yourself, what’s the current state of your mouth? Is it sparkling clean, or is there tartar and plaque buildup? Are you flossing daily? Do you brush at least twice a day? Do you rinse with some type of mouthwash after brushing? Do you do any type of oil pulling (coconut, sesame)? Do you brush with the proper pressure (not too hard, not too light)? Are you using a quality toothbrush (soft bristles preferably)? Is your toothpaste a good one? Would you be able to tell the difference between a good toothpaste and something that isn’t good?
What’s your diet like? Do you eat foods that support, nourish, and alkalize you? Do you keep your sugar intake reasonably low? Are you getting enough calcium in your diet, enough silica, enough other vitamins and minerals that support healthy gums and teeth?
From what you mentioned it sounds like the field is already doing something for you. Captain definitely is a miracle-worker, but with certain things you need to meet him halfway and do your part (and be patient). If you have major enamel erosion and have had other dental work done, it’s because your level of self care needs to be better when it comes to your dental health. Your habits need to change. It’s going to take some time to reverse the years of damage and erosion.
So ask yourself: Have you changed your habits to that of someone who has an amazingly clean and healthy mouth? Or are your habits the same as they have always been, with you somehow expecting miraculously different results? Like everything in the universe it comes down to simple cause and effect.
