Sensodyne Pronamel Fresh Wave Toothpaste, Fresh Breath, 4 oz (Pack of 2) Help protect your enamel against the effects of acid erosion. Dentists have reported a growing dental health concern due to changing modern diets: acid erosion. Even teeth without cavities can be affected. Acids in everyday food such as some fruit and acidic drinks, like orange juice and wine, can dissolve minerals from teeth, softening the enamel surface which is then more easily worn away. As the enamel becomes thinner, teeth can become visibly less white, weaker and sensitive. Sensodyne Pronamel Toothpaste Fresh Breath is formulated to help protect against the effects of acid erosion. It also contains fluoride providing the benefits of a regular toothpaste. Use Sensodyne Pronamel Toothpaste Fresh Breath whenever you normally brush to freshen breath, help protect teeth against the effects of acid erosion, and strengthen and re-harden enamel. p>Sensodyne Pronamel Gentle Whitening Toothpaste Twin Pack is designed to build increasing protection against tooth sensitivity. Gentle Sensodyne Whitening Toothpaste will harden enamel, protect against the effects of acid erosion, aid in the prevention of dental cavities and whiten tooth enamel simultaneously. Sensodyne Pronamel Toothpaste protects your teeth against sensitivity to cold, heat, acids, sweets and contact.
