Do Crest Whitestrips Expire

Procter & Gamble sues company for patent infringement

Procter & Gamble has filed suit against a local maker of oral care products, alleging patent infringement.

Cincinnati-based P&G, which makes consumer products, filed the lawsuit Monday against Grand Rapids-based Ranir, which makes store brand and branded oral care products, in the U.S. District Court of the Southern District of Ohio.

The lawsuit alleges Ranir’s private label tooth-whitening strips infringe on existing P&G patents related to the company’s Crest Whitestripes product. The patents in question are set to expire on June 6.

P&G is seeking injunctive and monetary relief, according to documents filed with the court.

Both Ranir and P&G declined to comment on the lawsuit.

P&G says the accused products are for sale under various brands: Walmart Equate Deluxe Whitening Strips; Walmart Equate Ultra Whitening Strips; Kroger Deluxe Whitening Strips; Kroger Premium Whitening Strips; and Kroger Ultra Whitening Strips.

Do Crest Whitestrips expire?

I have a box of Crest Whitestrips from quite a while ago and I want to use them but I'm wondering if they expire or loose their effectiveness.

I would look to see if there is an expiration or sell by date on the box

will expired crest whitestrips still work?

I got some Crest white strips and forgot about them. I recently started using them again and realized they expired in March. WIll they still work for me? Also, they say you can do 2 in a row, one right after the other. Are they just trying to make money

I think the Crest Whitestrips are actually better than whitening done at the dentist's office. The reason is because the Crest strips are not as fast-acting as the ones at the dental office which tend to cause severe tooth sensitivity.
