” Look for denture adhesive creams, like Fixodent, Polident, or Poligrip, with those labels. They mean the adhesive is long-lasting. If you only plan on using the cream for your fangs, choose the smallest tube, like a  2.5 oz (84 g) one, as you won’t need very much. You can buy denture cream from a pharmacy, drug store, or online retailer. Most tubes cost less than $5. Blot the tissue all over your top teeth and gums to remove any excess moisture. This helps the denture adhesive cream stick to your teeth better. Do this right before you’re ready to apply the fang. You can also use a paper towel or cotton swab instead of a tissue. Hold the tip of the tube at the wide top of the fang and squeeze a tiny amount of cream onto the fang. Keep the cream on the top half of the fang since that’s the part that will be against your tooth.  If you get too much on the fang or some on the pointy tip, wipe off the extra with a cotton swab. Use individual fangs instead of the ones that come in whole sets of teeth. You can buy fangs at a Halloween store or party goods store. Press the fang against your canine tooth so that the pointy tip is facing down and the concave side with the adhesive is covering your tooth. Hold it with your fingers until you can move your hand away and the fang stays in place.  To find your canine tooth, start at the middle of your upper teeth and count over 3 teeth. It’s the 3rd tooth from the center and is usually slightly pointier than the others. Use a timer or the clock app on your phone to keep track of the time if necessary. Repeat the same process on your other canine tooth. Squeeze a dot of denture adhesive cream onto the back of the fang, then hold it in place for 10 to 15 seconds on your tooth. Try to align the 2nd fang so that the pointy tip is as far down as the 1st fang and they’re even. Don't eat with your fangs in. If you do, you could crack the fangs or they could fall off. Instead, peel them off by pulling them forward and set them aside before you eat. Take them off before you sleep, too.  After eating, dab a little more denture cream on the back of each fang and stick them back onto your teeth. If you want the fangs to hold better, brush your teeth and dry them with a tissue before putting the fangs on again.
Buy a tube of denture adhesive cream that says “super” or “superior hold. Dry off your upper teeth and gums with a tissue. Squeeze a small dot of cream onto the backside of the fang at the top. Place the fang over your canine tooth and hold it for 10 to 15 seconds. Apply cream to the 2nd fang and press it into place over your tooth. Remove your fangs before eating or sleeping, then reapply them with more cream.
