I'm a dentist with 4 decades of experience. You don't need all those electronic bells and whistles. Oral B Pro 900 or Pro 1000 is great.

Just by reading your description (I didn’t watch the video) it sounds correct. There’s more than one proper technique, it just depends what you’re trying to achieve. Look up Bass brushing method, as this is the one we recommend to people 99% of the time. But if this doctor is someone like a periodontist or specialist of some kind, he may be recommending you a different way which is fine. We’re just gently trying to disrupt plaque on a regular basis, it’s definitely not like scouring dirty dishes. A lot of people aren’t brushing properly. Most of us get taught how to do it in 2nd grade and nobody teaches you again when you’re an adult (it’s different technique for children). As long as you’re removing plaque ok your hygienist might not have reviewed brushing with you. Next time you go for your appointment have them go over it with you. Some people are way too heavy handed. Holding the handle lightly in your fingertips, or using your non dominant hand are both little strategies we use especially in periodontist offices to help people avoid that autopilot muscle memory of scrubbing too hard that is so often happening. Always extra soft toothbrush no matter what. I prefer the Nimbus if you want to use manual, or Oral B with the gum care extra soft heads if you want electric. And finally recession can be caused by so many things. Hard brushing could be contributing, but if it’s generalized throughout your entire mouth I’d be looking more into clenching and grinding forces as a likely culprit. Things like history of braces can also affect recession, and so can an improper bite. There can be a lot of factors at play.

Yes brush your tongue or use a scraper daily. Huge for reducing oral bacteria. Oral B is much better than Sonicare imo but whatever you use, don’t apply pressure onto the tooth with it, just rest it lightly. You can flip the TB head vertically to help fit into those spaces, if the guy is a periodontist no need to be skeptical you can adopt his tips and benefit. He’s not being weird, I often have to tip my brush like that in the front teeth, the key is to make sure the toothbrush bristle is touching your gum tissue gently so basically whatever you have to do to attain that. The shape of the oral B is round so it might reach those areas for you without causing such a mess. I order the Nimbus on Amazon, it comes with a few in one pack I think. Periodontists like manual brushes because they are harder to hurt yourself with. Most people are too heavy handed with electric. Hygienists and dentists like electric because they typically do a better job of cleaning than manual. Two schools of thought, two valid viewpoints. Work with your hygienist to see what gives the best results for you.

I had my Oral-B (type 3764) for more than 10 years. Never noticed any mold issues, except a little bit of mildew at the base which is easy to clean. I also don’t really put any extra care into cleaning it

I have a 3757 which looks the same as yours but is much cheaper. It probably is legit the same toothbrush with yours having some marketed extra to push the price point 4x higher. Mine is always dripping water so I bet my handle has the same problem

Get the cheapest oral b that includes a pressure sensor and the quadrant timer. Anything else is a waste of money. I used to have the top of the range oral b with Bluetooth and an app, when it wore out I got a standard one because no one needs any of that shit.

I am a practicing general dentist and have used both. I used the oral b professional for many years before switching to the io. Both brushed well, but the io's battery was not very good. I then switched to the Philip sonicare and have been happy with it. I got the least expensive one I could, so I could see if I like it. I do and have continued to use it. To summarize, I would recommend either of those brands, just be careful with the io.

OralB Pro električna sa sensitive nastavcima. Ima tri modea i nikakve bluetooth smart gluposti. Ako prejako stisneš uspori se i signalizira jakim crvenim svjetlom. Zubi kasnije glatki kao polirani u 2min. Stomatologinja mi je rekla da koristim mekane nastavke. Kaže da su tvrdi dobri samo za čistiti gebis 😄 Ta električna mi dobro očisti iza osmica što sa običnom nisam mogao. Idem prema 50-toj i još imam sve zube.

Get the oral b pro. It runs like 30$ and its the best toothbrush on the market and it auto turns off if you push too hard, so it will protect your gums from further deterioration.
