What Is Acid Erosion of the Teeth?

Acid erosion is the wearing away of tooth enamel. Enamel is mostly calcium, which is dissolved away by acid quite easily. Food or drink with a pH of 5 or less can dissolve the enamel from teeth. 
What are the symptoms, signs and effects of acid erosion? 
Acid erosion can wear away the enamel and change the texture, shape and appearance of your teeth, and may also lead to tooth sensitivity. People often do not become aware of acid erosion until it has reached an advanced stage. Detailed dental examinations can help to detect acid erosion in its earlier stages. Here are the typical signs and effects of acid erosion:
1.  Transparency: Teeth may appear slightly "glassy" or transparent near their biting edges. This tends to be an earlier warning sign of acid erosion.

What Is the Best Tooth Brush to Buy?

There are two kinds of brushes: manual brushes and power brushes.

Sonicare Flexcare

Of the power brushes there are those requiring batteries and those with rechargeable stands. The head movement of the battery operated brushes (those you buy at Target for $6-$7) is not very effective. Look for a brush with its own rechargeable stand.  We recommend the higher end brushes: Sonicare or Oral-B.  The price runs about $90.00. The Sonicare has the conventional style brush head, long and thin. The Oral-B has a small, round head. Both are good brushes. It’s just a matter of preference regarding the brush head. The bristles in both the Sonicare and Oral-B are soft enough to prevent them causing recession. However, remember that when using a power brush not to push too hard against the teeth while brushing. Let the brush do the work.

Does It Matter What Kind of Floss I Use?

According to the studies it does not matter. We will discuss different types of floss and tell you why we prefer some flosses over others.
Dental floss is available in many forms and textures: waxed and unwaxed, flavored and unflavored, tape or ribbon, and in varying widths: thin, regular, or wide. Some floss has a fluoride coating to help prevent dental caries, but its effectiveness has not yet been proven.
