From Santa Maria Novella, Dentifricio Fior d'Iris / Iris toothpaste: "Toothpaste with a fresh aromatic flavor. It contains ireos powder, known since antiquity for its astringent and abrasive properties. The aroma of costmary gives the toothpaste a singular, minty-spicy taste while refreshing and deodorizing the mouth." Can you taste the iris? Is it delicious? I have no idea. $20 for 60g at Smallflower.
Another lemming from Floris, thanks to galbanumgal: Violet Mouthwash. "Modern violet tones meet Floris tradition with this concentrated mouthwash in a beautiful glass bottle. A breath freshening, glamorous and sophisticated approach to dental hygiene in just six beautiful drops, bringing grace to your morning routine as well as a touch of stately decadence for any bathroom shelf. [...] Just six drops applied to 60ml of warm water is all that is required and a 100ml bottle can be expected to last at least 2 months if used daily." $65 at Floris, and also available in Rose for the same price.
Boka's first toothpaste for kids: Orange Cream Space Paste. "Boka's first official kid's flavor, Orange Cream, has vibrant notes of oranges paired with creamy natural vanilla. The name, Space Paste, is a nod to NASA's invention of nano-hydroxyapatite (nHa) in the 1970's. The ingredient, once only enjoyed exclusively by astronauts, is now available to junior space voyagers." Fluoride free & SLS free, $12 for 113g at Beautyhabit.
From Marvis, the Tea Collection, with toothpaste in three flavors: Blossom Tea (black tea, exotic flowers, cherries and peaches); Creamy Matcha Tea (inspired by bubble tea from Taiwan) and Earl Grey Tea (bergamot and black tea). With fluoride, and available in 25 or 75 ml, or in a set of 3 x 25 ml. I don't think these are in the US yet, but you can order from Gents in Sweden, First in Fragrance in Germany, Fat Buddha in Scotland or Carter & Bond in England.
Oh, sure, I'll take one: Violette Menthe toothpaste from Ohlalá Paris. I can't find it in the US, but it's £5.80 at Makeup in the UK.
