My child is almost done teething, but I don't think that I would have been able to make it without teething tabs, teething biscuits, and a baby toothbrush. The teething tabs helped throughout the teething process. Sometimes I give her some when she is throwing a tantrum simply because they help to calm her down.
The teething biscuits were great; although they always ended up as a slimy mess stuck to the bottom of one of our feet. We only used teething biscuits through the early stages because when her molars were working their way through she would bite off large chunks. We also never used the Gerber biscuits because they broke more often than the flat kind, and they took longer to dissolve; in my mind posing a greater choking hazard.
The toothbrush was great for the last six months of her teething. We would brush her teeth and then let her chew on the toothbrush for a little while. FYI, there are also infant toothpastes on the market that are swallow safe. Getting her used to toothbrushes early is also a good idea. We brush her teeth twice a day, and she absolutely loves it. She often brings her toothbrush to us after eating to let us know she wants to brush.
