Dental Fluorosis: Too Much Fluoride is a Bad Thing

Dental fluorosis is a condition that occurs when the body takes in more fluoride than it needs. It is most common in children whose teeth and gums are still developing (typically before age 7). The result is discoloration of the teeth. In a mild form, the teeth get white lines or patches.  In more extreme cases, the enamel can turn yellow or brown, and the teeth can become mottled.

Fluoride is readily available, so it is important to monitor fluoride intake. Fluoride can be ingested from sources such as tap water, toothpaste and vitamins. Make sure your children use small amounts of fluoride toothpaste and rinse thoroughly to avoid swallowing it.

As with any oral health issue, consult your dentist regarding prevention or treatment of dental fluorosis.

Lemons Can Hurt Your Teeth

Cold lemonade on a hot day...  Lemon in hot tea on a cold day... They may both sound good to you, but your teeth may not agree. Lemons and lemon juice have a very high acid content which can irritate your gums and wear away the enamel on your teeth, leading to dental erosion. 

You can enjoy your lemons and still take care of your teeth. Some tips include: drink acidic beverages with a straw, to minimize their contact with your teeth and drink water after you eat to help to wash away the acid.

Another thing to do, which may seem counterintuitive, is to wait an hour or so after eating or drinking acidic food before you brush your teeth. Abrasive materials contained in some toothpastes may damage your enamel, which gets weakened by the acid.

Of course, your dentist can check for signs of dental erosion.
