Bought with my own money, Cryo Dentimade Season 2 Ultra-fine Bristle Toothbrush

The toothbrush I used before had regular bristles, so my gums felt a little sore after brushing, but the Cryo Dentimate Season 2 ultra-fine bristle toothbrush has incredibly soft bristles, so it doesn't put any strain on my gums and doesn't hurt at all.

Since it has ultra-fine bristles, it is less durable than a regular toothbrush, but it is good to replace toothbrushes frequently anyway, and it is affordable, so it is good to use.
