Top experts advocate these tips to protect your teeth and gums :
1) Stick to Straws - teas, coffee, juice, wine and soda can leave stains on your teeth and weaken them. Use a straw to fix this and if you are not used to drinking your beverages via straws, swish your mouth with water when you're done sipping.
2) End your meal with Cheese - carbs like rice and pasta encourage bacteria in your mouth to produce enamel - eating acids. Eating calcium rich foods helps to boost tooth protecting minerals. Try to finish off your meals with a bite of cheese to neutralize your carb meal.
3) Keep your dentist in the loop about your meds - blood pressure meds, antihistamines and antidepressants can interfere with your ability to make saliva. This can lead to dry mouth and a higher risk of oral disease since decreased saliva production allows bacteria and plaque to build up faster. Discuss your meds with your dentist and find out if there are any ways to work around this.
