My trusty 16 year old sonicare toothbrush, a tongue scraper, and a water pik make it so I barely get fuzzy teeth unless I eat a bunch of sweets or crackers. I also swish with OralB gum detoxify mouthwash every once in a while, but I didn’t have much plaque even without using it.
The other oralb washes aren’t as great imo, but the gum detoxify has zinc and cetylpyridinium chloride in it which both inhibit bacteria. No alcohol in it either which is what causes most mouthwashes to burn. It does cause you to spit out a white film immediately after which I assume is dead bacteria. Never had any irritation with it and a doctor actually recommended it to me when I had strep throat which it helped.
Also Walmart carries a sonicare 1100 that is only around $20. I use that when I travel instead, and it’s just as good as my older more expensive electric toothbrush.
They could be Phillips dual color mini LED lights. Target currently has a few versions of the strings and the specs list 3mm LED. The exact names on target are “Philips 210ct LED App Controlled Christmas String Lights Dual Color” or “Philips 200ct LED App-Controlled Color Changing Create Motion Dome String Lights” You could probably use the bulbs in your current lights, but the strings are kind of pricey.
There is another maybe from Sylvania that doesn’t list the bulb size. Amazon has “Sylvania Stay-Lit Platinum 100-Count Color Changing LED Mini Dual Lights”. Apparently Costco also used to sell these, but doesn’t have them right now .
It might not be possible to find just a few replacement bulbs, but I wish you luck.
