Why Tooth Whitening<br />

Toothpastes<br />

Don’t Work<br />

HEALTH<br />

If you’re looking for that dazzling smile<br />

and want to achieve it with teeth whitening<br />

toothpastes, better save your money.<br />

“They’re worthless,” Kira Watson,<br />

registered dental hygienist at the office<br />

of Fausto R. Prato, DDS located in<br />

Stockton said in a private interview. “If<br />

you want white teeth, the professional<br />

kits or professional in-office whitening<br />

treatments work. The problem (with the<br />

toothpastes) is that they can be extra<br />

abrasive and wear away the enamel<br />

layer, which will then make teeth whitening<br />

more difficult.”<br />

But there’s more to this story about why<br />

they don’t work.<br />

Tooth Anatomy<br />

The connection of abrasiveness to teeth<br />

whitening is actually simple but you<br />

have to understand a little about tooth<br />

anatomy first.<br />

The structure of a tooth has three primary<br />

layers: the crown or enamel, the dentin,<br />

and the pulp. The crown or enamel<br />

of the tooth is the white visible part, and<br />

it’s composed of a material harder than<br />

bone. In fact, tooth enamel is the hardest<br />

material found in the body.<br />

The dentin layer is a yellow layer. This<br />

layer is composed of tiny tubules that<br />

connect to the nerve within the pulp.<br />

It’s a sensitive layer, that is, sensitive to<br />

what you do to the tooth.<br />

Combine the exposure of the dentin<br />

part of the tooth with normal everyday<br />

stains on the enamel from coffee,<br />

tea, chocolate, pomegranates,<br />

blueberries, blackberries and other<br />

foods and you have the recipe for<br />

discolored, yellow teeth.<br />

If you use a very abrasive toothpaste<br />

that wears away the enamel<br />

quicker in an attempt to remove<br />

stains, you end up with a formula<br />

for more stains that are harder<br />

to remove.<br />

And the big problem is that<br />

many of the top teeth whitening<br />

toothpastes are in fact,<br />

abrasive.<br />

stands for medium abrasiveness,<br />

L for low abrasiveness.<br />

ranking from 0 to 100, 100<br />

equivalent to top ranking.<br />

M = medium abrasiveness L = low abrasiveness Scale is based on a ranking from 0 to 100, 100 equivalent to top ranking.<br />

And the pulp layer is the layer with<br />

the blood vessels and nerves. The pulp<br />

layer is also another sensitive layer.<br />

<strong>How</strong> Teeth Whitening Toothpastes Affect<br />

Tooth Anatomy<br />

As we age, our enamel starts to wear thin.<br />

The more you expose the dentin layer, the<br />

more you expose the yellow color of that<br />

layer, the dentin, of the tooth.<br />

What’s a Consumer to Do?<br />

To answer this question, your dentist is<br />

really the best resource. <strong>How</strong>ever, there<br />

are some recommendations you can<br />

start initiating right now:<br />

1 Since toothpastes are the lowest on<br />

the totem pole of effectiveness at creating<br />

whiter teeth, use a low abrasive<br />

toothpaste and save your enamel.<br />

2 Brush your teeth immediately after<br />

eating. This will remove any stains that<br />

resulted from eating or drinking foods<br />

that have pigments that cause staining.<br />

3 Consider professional teeth whitening<br />

kits or professional laser teeth whitening.<br />

These work quickly and often result<br />

in teeth that are 7 to 10 shades lighter.<br />

Then continue your good habits #1 and<br />

#2 to maintain the brightness.<br />

As the dental hygienist said, “Teeth whitening<br />

toothpastes don’t work. They just<br />

remove the external stains. When they’re<br />

abrasive, they can cause problems. <strong>Your</strong><br />

best bet is to use the professional bleaching<br />

agents obtained from the dentist.<br />

They’re stronger and get the job done.”<br />
