Defoe made the move to the Vitality Stadium in the summer in the hope of cementing his place in England's World Cup squad, but the 35-year-old knows he must produce the goods consistently in the Premier League, with only one goal so far.
Goals have been hard to come by for last season's topscorer Joshua King, who has two goals in all competitions, and the imminent return of Callum Wilson from injury will be a welcome boost.
Howe, though, is not overly concerned by his team's collective drop in strike rate, having netted just four times in the Premier League from seven matches.
"Goalscoring has been a problem for us this season, which isn't like us, but hopefully we can turn that round from now on," Howe said, in quotes published on the club's official website.
"When you look at Jermain Defoe, he has had big chances in all the games and when you look at his career if he gets those chances he will score.
"It is a team problem and I back Jermain to score a lot of goals for us in the future."
Howe added: "We are almost there in terms of getting consistent results. The problem at the start was that the performances weren't there, but we have improved now and that gives us confidence."
